Protein Function
Integrin alpha-4/beta-7 (Peyer patches-specific homing receptor LPAM-1) is an adhesion molecule that mediates lymphocyte migration and homing to gut-associated lymphoid tissue (GALT). Integrin alpha-4/beta-7 interacts with the cell surface adhesion molecules MADCAM1 which is normally expressed by the vascular endothelium of the gastrointestinal tract. Interacts also with VCAM1 and fibronectin, an extracellular matrix component. It recognizes one or more domains within the alternatively spliced CS-1 region of fibronectin. Interactions involves the tripeptide L-D-T in MADCAM1, and L-D-V in fibronectin. Binds to HIV-1 gp120, thereby allowing the virus to enter GALT, which is thought to be the major trigger of AIDS disease. Interaction would involve a tripeptide L-D-I in HIV-1 gp120. Integrin alpha-E/beta-7 (HML-1) is a receptor for E-cadherin.

Application Protocols

Item-specific, tested applications and recommended dilutions

• Not specified for this item; refer to CoA/Spec Sheet.

General protocol outlines (non-item-specific; to be optimized by the user)

• Flow cytometry (surface staining):
  • Prepare single-cell suspension; block Fc receptors.
  • Incubate cells with serial dilutions of primary Rat anti-ITGB7 mAb for 20–30 min at 4°C in staining buffer.
  • Wash, then detect with species-appropriate secondary if unconjugated; acquire data with proper compensation controls.
• Immunofluorescence (cell or tissue):
  • Fixation/permeabilization only if epitope is preserved; many integrin epitopes are conformational—prefer non-denaturing conditions.
  • Block, incubate with primary, wash, and detect with labeled secondary.
• Immunoprecipitation:
  • Lyse under mild, non-denaturing conditions (e.g., NP-40, digitonin) to preserve integrin complexes.
  • Couple antibody to Protein G/A matrix as compatible with Rat isotype; capture, wash, and elute under gentle conditions.

Important note

• Because clone, isotype, and validation data are not provided for this item, the above are general templates only. Empirically determine optimal conditions and include appropriate controls.

Biological Roles

General/literature knowledge about the target (Integrin β7)

• Integrin β7 (ITGB7) is a β integrin subunit that pairs with α4 (forming α4β7) or αE (forming αEβ7, CD103). These heterodimers mediate leukocyte adhesion and homing.
• α4β7 binds to MAdCAM-1, directing lymphocyte trafficking to gut-associated lymphoid tissue. αEβ7 binds E-cadherin on epithelial cells, promoting lymphocyte retention at mucosal sites.
• Signaling: Ligation triggers outside-in signaling that influences cell migration, survival, and activation; inside-out signaling via chemokines modulates integrin affinity and avidity.
• Expression: Prominent on subsets of T cells, B cells, and dendritic cells involved in mucosal immunity.

Relevance for antibody use (general)

• Phenotyping: Antibodies against β7 help define gut-homing T-cell subsets and regulatory populations.
• Functional blocking/activation: Certain clones can block ligand binding or report activation state; functional attributes for this specific item are not specified.

Item-specific note

• This product is a Rat mAb against Integrin β7; species reactivity, clone, and functional characterization are Not specified for this item; consult the CoA/Spec Sheet for details before designing experiments.

Buffer Applications

Item-specific facts (from Product Data)

• Formulation: PBS only; Azide Free; Carrier Free.

Practical buffer guidance (general)

• Working buffer: Use PBS (e.g., 10 mM phosphate, 137 mM NaCl, 2.7 mM KCl, pH ~7.4) for routine dilutions. Filter-sterilize (0.22 µm) to minimize bioburden.
• Blocking/assay buffers: For immunoassays where carriers are permissible, add 0.1–1% inert protein (e.g., serum albumin) and/or 0.05–0.1% non-ionic surfactant (e.g., Tween-20) to reduce nonspecific binding. Note: The stock is Carrier Free; additions apply to user-prepared working buffers only.
• Live-cell compatibility: Azide-free formulation is suitable for live-cell exposure; maintain isotonicity and neutral pH. Avoid azide and other metabolic inhibitors in live-cell assays.
• Storage buffer considerations: Because this item is Do not freeze and lacks cryoprotectants, keep at 2–8°C. For short-term aliquots, maintain sterility and minimize headspace to reduce oxidation.

Recipe hints (general)

• PBS (1×): Dissolve commercial PBS tablets per manufacturer instructions or prepare from sodium phosphate dibasic/monobasic, NaCl, and KCl; adjust pH 7.2–7.4; filter-sterilize.
• For flow cytometry staining buffer: PBS + 1–2% serum (species-matched) + 2 mM EDTA (optional) to reduce cell clumping; omit serum for serum-sensitive readouts.

Green Alternatives

Context

• As a PBS-formulated, Azide Free, Carrier Free antibody, this product already avoids hazardous sodium azide and organic solvent carriers, reducing environmental and safety burdens relative to azide-preserved reagents.

Greener handling options (general)

• Preservatives: If antimicrobial control is needed, consider short-term sterile filtration and aseptic handling rather than adding azide, particularly for cell-based work.
• Packaging and waste: Use right-sized aliquots to minimize waste from expired material. Rinse empty vials to remove protein residues before recycling where allowed.
• Buffer exchange: If buffer modification is required, use low-waste spin concentrators rather than dialysis with large buffer volumes.

Comparison of preservative strategies (general)

• Sodium azide: Effective antimicrobial but acutely toxic and incompatible with many enzymatic assays and live cells.
• ProClin/biocides: Provide preservation but can pose aquatic toxicity; assess compatibility and disposal requirements.
• Aseptic technique + cold-chain: Eliminates chemical preservatives; relies on rigorous sterile handling and refrigerated storage—aligned with this item’s Do not freeze requirement.

Trade-offs

• Azide-free and carrier-free formats demand more careful aseptic technique and may have shorter in-use shelf life; they provide cleaner backgrounds and higher compatibility with sensitive assays and live systems.

Pharmaceutical Uses

Applicability

• This is a research-grade Rat monoclonal antibody. No pharmacopeial status or clinical/formulation claims are made. For research use only.

General information (non-item-specific)

• Monoclonal antibodies in pharmaceutical contexts require stringent GMP manufacturing, defined isotype, glycosylation control, and validated stability profiles—none of which are specified for this research reagent.
• Excipient considerations for therapeutic mAbs (for context): Formulations often include buffers (histidine, acetate), stabilizers (sugars, polyols), surfactants (polysorbates), and tonicity agents. This product is PBS only and Carrier Free, Azide Free, which is suitable for laboratory research but not equivalent to GMP formulations.

Practical lab utility

• Useful as a reference reagent in preclinical assay development (e.g., ligand-binding assays, cell-based assays, analytical controls), subject to verification of performance characteristics in the intended method.

Item-specific note

Considerations—greater propensity for adsorption losses at low concentration; use low-bind plastics and minimize dilutions.
• Azide Free: No sodium azide preservative. Advantages—compatible with live-cell applications, cell-based assays, and enzyme-mediated detection systems where azide is inhibitory or toxic. Considerations—higher risk of microbial growth; maintain aseptic handling and store strictly at 2–8°C.
• Validated: Indicates that the product has undergone manufacturer validation. Specific validated applications, species reactivity, and performance metrics are Not specified for this item; refer to CoA/Spec Sheet for details.
• PBS Only: Formulated solely in phosphate-buffered saline without additional excipients. Advantages—well-defined buffer system, compatible with most immunoassays. Considerations—lack of cryoprotectants means Do not freeze, and absence of surfactants may increase surface adsorption at low concentrations.

Recommended QC checks by end-users (general guidance)

• Verify protein content (e.g., A280) and integrity (SDS-PAGE, reducing/non-reducing) upon receipt when feasible.
• Confirm application-specific performance (e.g., titration curves in your assay format) since application details are not specified here.

Reaction and Applications

Item-specific facts (from Product Data)

• Application details are not provided. Manufacturer Applications: Not specified.

General/literature context for Integrin β7 antibodies (non-item-specific guidance)

• Use cases: Frequently employed to detect, quantify, or perturb ITGB7 on lymphocytes and gut-homing T cells in immunology research.
• Assay modalities: Commonly used in flow cytometry (cell-surface staining), immunofluorescence (IF), immunohistochemistry (IHC) on frozen sections, immunoprecipitation (IP), and occasionally Western blot (WB) depending on epitope exposure. For functional studies, azide-free formulations (as here) are compatible with cell-based assays.
• Practical tips:
  • Titration: Determine the optimal antibody-to-cell ratio empirically (e.g., serial 2-fold dilutions in flow cytometry) to balance signal and background.
  • Blocking: Use Fc-blocking reagents appropriate to the sample species to reduce non-specific Fc receptor binding.
  • Compensation/controls: Include isotype controls, fluorescence-minus-one (FMO) controls, and viability dyes when using conjugated secondary antibodies.
  • Antigen stability: Integrin epitopes can be conformational; non-denaturing conditions favor recognition. For WB, native or mild denaturation protocols may be required; verify in pilot tests.
  • Conjugation: Carrier-free format facilitates direct conjugation to enzymes or fluorophores; confirm preservation of binding after conjugation by running a small-scale pilot.

Note: Specific working dilutions, clones, and validated applications for this item are not provided; consult the CoA/Spec Sheet.

Solvent Selection

Applicability

• This product is an aqueous antibody preparation. Traditional organic solvent selection is not applicable.

Buffer/medium considerations (item-specific and general)

• Formulation: PBS only (item-specific). Neutral pH buffers minimize antibody denaturation and preserve antigen-binding.
• Additives: This item is Carrier Free and Azide Free. If long-term storage or frequent handling is expected, users may optionally prepare working dilutions with low levels of stabilizers (e.g., inert proteins or non-ionic surfactants) as appropriate for the assay; do not add azide to live-cell applications.

Miscibility and compatibility (general)

• Miscible with other physiological buffers (e.g., HBSS, Tris-buffered saline), but buffer exchange can shift binding behavior for some antibodies—validate after buffer changes.
• Avoid organic solvents, strong acids/bases, or high concentrations of chaotropes, which can denature Ig proteins.

When to choose PBS vs alternatives (general guidance)

• PBS: Default for most immunoassays and flow cytometry; isotonic and maintains near-physiological ionic strength.
• Tris-buffered saline (TBS): Preferred when phosphate interferes with detection chemistries (e.g., certain ALP-based systems) or metal-dependent interactions.
• HEPES-buffered saline: Useful for CO2-independent live-cell work due to superior pH buffering near physiological pH.
