Protein Function

In cooperation with other chaperones, the Hsp70 family stabilize preexistent proteins against aggregation and mediate the folding of newly translated polypeptides in the cytosol as well as within organelles. These chaperones participate in all these processes through their ability to recognize nonnative conformations of other proteins. They bind extended peptide segments with a net hydrophobic character exposed by polypeptides during translation and membrane translocation, or following stress-induced damage. In case of rotavirus A infection, serves as a post-attachment receptor for the virus to facilitate entry into the cell.Tissue specificity: HSPA1B is testis-specific.

Application Protocols

Tested applications, recommended dilutions, and positive-control samples for this specific item are not specified; refer to the CoA/Spec Sheet.

General best-practice frameworks (not item-specific):

• Aliquoting: Thaw on ice, mix gently, and aliquot into single-use volumes to avoid repeated freeze–thaw. Use low-bind tubes.
• Western blot: Load a heat-shock positive lysate (e.g., cells incubated at 42–45°C for 30–60 min) alongside a negative control. Optimize blocking reagent (BSA vs milk) according to detection system.
• IF/ICC: Fix (e.g., 4% paraformaldehyde), permeabilize (0.1–0.3% Triton X-100 if intracellular), block (1–5% BSA/serum), incubate with primary antibody, then fluorophore-conjugated secondary matched to mouse IgG subclass.
• IHC: Perform antigen retrieval (citrate pH ~6 or Tris–EDTA pH ~9), block endogenous peroxidase if using HRP, and include isotype controls.
• IP/Co-IP: Pre-clear lysates, titrate antibody-to-lysate protein ratio, and validate specificity by competitive elution or detection of known interacting partners.
• ELISA: Use azide-free buffers for HRP/TMB systems; establish a standard curve with recombinant Hsp70 to quantify.

Documentation: Record lot number, storage history, and working dilutions for repeatability. For precise, item-validated conditions, consult the CoA/Spec Sheet.

Biological Roles

Target: Hsp70 (heat shock protein 70 family) — general biology (literature; not item-specific claims).

• Function (literature): Hsp70 proteins are ATP-dependent molecular chaperones that assist in nascent polypeptide folding, prevent aggregation, facilitate refolding of stress-denatured proteins, and coordinate protein translocation across membranes. They cooperate with co-chaperones (e.g., Hsp40/DNAJ, nucleotide exchange factors) to cycle between high- and low-affinity substrate states.
• Cellular localization (literature): Predominantly cytosolic for HSPA1A/HSPA1B; other family members localize to organelles (ER: BiP/GRP78, mitochondria: mortalin/GRP75). Inducible and constitutive isoforms display distinct stress responsiveness.
• Regulation (literature): Transcription driven by heat shock factor 1 (HSF1) under proteotoxic stress (heat, oxidative stress, toxins). Post-translational modifications modulate activity and interactions.
• Interactome (literature): Binds exposed hydrophobic segments of client proteins; interacts with components of the proteostasis network, proteasome, and autophagy pathways.
• Experimental utility (general): Antibody detection of Hsp70 is widely used as a marker of cellular stress responses, protein-folding capacity, and quality control mechanisms across many model systems.

Note: Specific isoform recognition, epitope mapping, and cross-species reactivity for Hsp70 Mouse mAb are not specified for this item; refer to the CoA/Spec Sheet for definitive target details relevant to your system.

Buffer Applications

Appropriate buffer systems are essential for antibody performance. This product is carrier-free and azide-free; select buffers that preserve activity while matching your assay.

General buffer systems (not item-specific):

• PBS, pH 7.2–7.6: Widely used for storage, dilutions, WB, IF/ICC, IHC. Add 0.05% Tween-20 (PBST) for washing steps to reduce nonspecific binding.
• TBS, pH 7.4–8.0: Preferred for alkaline phosphatase detection and in workflows where phosphate may interfere.
• Blocking buffers: 3–5% BSA or casein in PBS/TBS for WB and IHC/IF; choice depends on secondary antibody and detection chemistry. Serum from the host species of the secondary can reduce Fc-mediated background.
• Antigen retrieval (IHC): Citrate buffer (10 mM, pH ~6.0) or Tris–EDTA (10 mM Tris, 1 mM EDTA, pH ~9.0) for heat-induced epitope retrieval; optimize by tissue and fixation.
• Storage additives: If compatible with downstream assays, 10–50% glycerol can be added to aliquots for −20°C storage to mitigate freeze–thaw; no preservatives are included by default in this product.

Practical tips:

• Filter-sterilize buffers (0.22 μm) and use aseptic technique because the product is azide-free.
• Match salt and detergent concentrations between antibody diluent and wash buffers to stabilize binding equilibria and reduce background.

Item-specific buffer composition, pH, and recommended diluents are not specified; refer to the CoA/Spec Sheet.

Green Alternatives

This product is an aqueous antibody reagent; green chemistry considerations focus on buffer selection, preservative choices, and minimizing hazardous waste rather than solvent replacement.

Greener practice options (general guidance):

• Buffer systems: Prefer PBS or TBS prepared from high-purity salts and ultrapure water. These buffers are non-volatile and low-toxicity compared to organic solvent systems.
• Preservatives: Being azide-free eliminates the handling of sodium azide, a toxic and environmentally persistent biocide. If preservation is needed, consider low-toxicity alternatives at minimal effective concentrations and validate assay compatibility.
• Blocking agents: Use biodegradable proteins (e.g., casein, BSA) sourced responsibly; avoid milk powders with phosphatases when using AP detection.
• Detection systems: Favor HRP chemiluminescence substrates with reduced hazardous by-products or fluorescent readouts that avoid chromogenic heavy metals. Dispose of substrates according to local regulations.
• Process efficiency: Aliquot to reduce freeze–thaw waste; optimize antibody titers to minimize consumption; consolidate washing steps with automated platforms to reduce buffer volumes.

Trade-offs (general):

• Azide-free formulations improve environmental and biosafety profiles but may require stricter aseptic handling or cold-chain vigilance to avoid contamination.
• Some green preservatives (e.g., ProClin-type isothiazolinones) can interfere with sensitive enzymes or cell assays; always perform compatibility checks.

Always follow institutional green-lab guidelines and dispose of proteinaceous and chemiluminescent waste streams appropriately.

Pharmaceutical Uses

This product is designated For research use only and is not intended for human or veterinary diagnostic or therapeutic applications.

Formulation/manufacturing context (general, non-clinical):

• Carrier-free, azide-free antibodies are commonly selected for custom conjugation (fluorophores, enzymes, nanoparticles) or as analytical reagents in bioprocess development (e.g., ELISA-based product quality assays) where excipients and preservatives could interfere.
• For process analytics, low-background reagents facilitate sensitive detection of stress markers (e.g., Hsp70) in cell culture monitoring. Any use in GMP/QC environments requires independent qualification and documentation.
• Exact compliance with pharmacopeial monographs is not claimed; no pharmacopeia status is provided for this item.

Quality and Grades

The following quality descriptors are provided for this item; definitions are given to clarify their practical implications for experimental design.

Item-specific quality descriptors (from Product Data):

• Carrier Free: Supplied without protein carriers (e.g., BSA, gelatin). Advantages include clean conjugation chemistry (e.g., enzyme/fluorophore labeling) and minimized background in sensitive assays. Users may add their own stabilizers post-aliquoting if compatible with assays.
• Azide Free: No sodium azide preservative. Beneficial for live-cell applications, enzyme activity assays (e.g., HRP), and conjugation workflows that are azide-sensitive (e.g., click-chemistry variants). Requires rigorous aseptic handling to avoid microbial contamination.
• ExactAb™: Brand/line indicator. Specific platform attributes (e.g., recombinant production, lot-to-lot consistency) are not specified for this item; refer to CoA/Spec Sheet for details.
• Validated, High Performance: Indicates in-house validation to meet performance expectations; exact validation methods (WB, IHC, IF, ELISA, etc.), species reactivity, and sensitivity/linearity data are not specified for this item; refer to CoA/Spec Sheet.

What this means in practice (general):

• Expect low background from absence of carriers and azide; however, the formulation may be less resistant to handling stress. Aliquoting and cold-chain adherence are critical.
• For regulated workflows, document batch/lot and request CoA including purity, endotoxin (if applicable), and residual host-cell proteins, if relevant.

If you require application-specific validation (e.g., WB on mouse lysates), consult the CoA/Spec Sheet or request validation data for your intended use.

Reaction and Applications

As an antibody reagent, Hsp70 Mouse mAb is used in immunoassay “binding reactions” rather than chemical synthesis. The following outlines typical research applications and practical considerations. Item-specific tested applications are not provided and should be confirmed from the CoA/Spec Sheet.

Typical applications (general):

• Western blot (WB): Detection of denatured Hsp70 in cell/tissue lysates following SDS-PAGE and transfer.
• Immunofluorescence (IF)/immunocytochemistry (ICC): Localization of Hsp70 in fixed cells/tissues; permeabilization and blocking conditions can strongly influence signal.
• Immunohistochemistry (IHC): Detection in formalin-fixed paraffin-embedded (FFPE) or frozen sections with appropriate antigen retrieval.
• Immunoprecipitation (IP)/Co-IP: Enrichment of Hsp70 or its complexes from lysates for downstream MS or WB.
• ELISA: Plate-based quantification using captured or directly coated antigen; azide-free formulation favors HRP-based detection.

Practical tips (general):

• Optimize antibody dilution via checkerboard titration; use positive controls known to express Hsp70 (e.g., heat-shocked cells) and negative/knockdown controls when available.
• Maintain cold conditions and include protease inhibitors in lysis buffers to preserve Hsp70 and complexes.
• For conjugations (biotin, HRP, fluorophores), carrier-free formulation enables efficient labeling; control degree of labeling to preserve affinity/signal.

Note: Specific reactivity, clones, and validated applications for this product are not specified; verify with the CoA/Spec Sheet prior to critical experiments.

Reaction Conditions

Not directly applicable in the context of chemical reactions. For immunoassay “binding reactions,” conditions depend on the platform and are typically optimized empirically.

General guidance for common assay conditions (literature/best practice; not item-specific):

• Western blot: Primary antibody incubations commonly at 4°C overnight or 1–2 h at room temperature in PBS/TBS with 1–5% BSA. Wash with PBST/TBST. Optimize concentrations per membrane and antigen load.
• IHC/IF: Blocking for 30–60 min; primary incubation 1–16 h depending on antigen abundance and fixation; antigen retrieval buffers and permeabilizers (e.g., 0.1–0.3% Triton X-100) as required.
• ELISA: Coating antigen overnight at 4°C; primary incubation 1 h at room temperature; stringent washes to reduce background. Use azide-free buffers for HRP-based detection.
• IP/Co-IP: Incubate lysates with antibody 1–4 h at 4°C with gentle mixing, capture with Protein A/G resins appropriate for the mouse isotype (isotype is not specified; test A vs G binding).

Item-specific working dilutions, incubation times, and verified platforms are not specified for this item; refer to the CoA/Spec Sheet and perform pilot optimizations.

Safety and Handling

This is a research-use-only antibody preparation. While proteins are generally considered low hazard, proper laboratory hygiene and PPE are required.

GHS/SDS information (item-specific):

• Signal word: Not specified for this item; refer to SDS.
• H-statements: Not specified for this item; refer to SDS.
• GHS classification/pictograms: Not specified for this item; refer to SDS.

Handling recommendations (general best practices):

• Wear appropriate PPE: lab coat, gloves, and eye protection when handling solutions and during aliquoting.
• Work on ice for prolonged manipulations to reduce proteolysis or denaturation.
• Use sterile technique to prevent microbial contamination, especially as the product is azide-free (no biocidal preservative).

Incompatibilities and cautions (general):

• Avoid repeated freeze–thaw cycles (Product Data). Aliquot upon first thaw to single-use volumes.
• Avoid strong oxidizers, extreme pH (<5 or >9), and high shear or vigorous vortexing that can denature or aggregate antibodies.
• Do not add sodium azide if downstream applications involve peroxidase-based detection or live-cell exposure; azide inhibits HRP and is toxic to cells.

First aid (general guidance; defer to SDS):

• Skin/eye contact: Rinse with water. Remove contaminated clothing.
• Ingestion/inhalation: Seek medical advice if exposure is suspected.

Always consult the SDS for authoritative safety, spill response, and disposal guidance for your specific lot.

Solvent Selection

Antibodies are handled in aqueous buffers rather than organic solvents. This product is carrier-free and azide-free; compatible aqueous systems and excipients should be selected based on the intended application.

General buffer guidance (not item-specific):

• Primary buffers: PBS (10–50 mM phosphate, ~150 mM NaCl, pH 7.2–7.6) or TBS (25–50 mM Tris, ~150 mM NaCl, pH 7.4–8.0) commonly maintain antibody stability.
• pH/ionic strength: Neutral pH with physiological ionic strength reduces aggregation and nonspecific binding. Low-salt conditions can favor conjugation reactions.
• Additives (if compatible with downstream use): 10–50% glycerol for freeze–thaw protection; 0.1–0.5% trehalose or sucrose as lyoprotectants; 0.01–0.1% nonionic detergents (e.g., Tween-20) for surface passivation. None are included by default in this item per Product Data; add only as needed.
• Preservatives: Product is azide-free; if storage at 2–8°C is necessary and compatible, users may add alternative preservatives (e.g., ProClin) with awareness of assay interference. For HRP-based assays or cell work, avoid azide.

When to choose PBS vs TBS (general comparison):

• PBS: Preferred for most immunoassays and mammalian protein work; phosphate can interfere with some metal-catalyzed conjugations.
• TBS: Preferred for alkaline phosphatase detection (phosphate inhibits AP) and some membrane-based assays.

Avoid organic solvents (e.g., DMSO, acetonitrile) that denature proteins unless used at very low percentages in specialized protocols.

Storage and Reconstitution

Item-specific storage/shipping:

• Storage conditions: Store at −20°C. Avoid repeated freezing and thawing (Product Data).
• Shipping: Ice chest + ice pads (Product Data) — maintain cold chain upon receipt.

Reconstitution and handling:

• Physical state (liquid vs lyophilized) and initial concentration are not specified for this item; refer to the CoA/Spec Sheet.
• If lyophilized (general guidance, not item-specific): Reconstitute with sterile, neutral pH buffer (e.g., PBS) to the desired concentration. Allow to dissolve gently on ice without vigorous mixing. If conjugation is planned, choose a carrier-free, amine-compatible buffer (avoid Tris for NHS-ester labeling).
• If received in solution (general guidance): Mix gently by inversion; avoid vortexing. Inspect for turbidity/precipitation.

Aliquoting and long-term stability (general):

• Aliquot into low-bind, sterile tubes sized for single use. For −20°C storage, consider adding glycerol (10–50%) to user-prepared aliquots if compatible with downstream assays; do not add sodium azide if planning HRP-based detection or live-cell work.
• Avoid multiple freeze–thaw cycles; thaw on ice and keep cold during use.

Shelf life and specifications:

• Appearance, exact buffer composition, pH, protein concentration, and expiry are not specified for this item; refer to the CoA/Spec Sheet.
• For any deviations from recommended storage, perform small-scale functional checks before critical experiments.
