Übersicht

ITS Plus consists of recombinant human IGF-1, recombinant transferrin, sodium selenite and other components. It contains no phenol red. As a supplement for basal cell culture media, it can reduce the usage of fetal bovine serum during the culture of various cells, and is commonly applied in serum-free or low-serum cell culture.

IGF-1 is a polypeptide hormone with pleiotropic anabolic effects on mammalian cells. It facilitates the uptake of glucose and amino acids, lipogenesis, transport of monovalent cations and phosphates, as well as the synthesis of proteins and nucleic acids. Transferrin acts as an intracellular iron carrier and helps mitigate the toxicity of oxygen free radicals and peroxides. Sodium selenite serves as a cofactor for glutathione peroxidase and other proteins, functioning as an antioxidant in culture media.

Product Features:

1. This product is sterilized by filtration.

2. Free of animal-derived components, it supports low-serum and serum-free cell culture.

3. Applicable to the culture of various cell types and can promote cell growth.

4. Compatible with a wide range of culture media. It effectively boosts cell growth, facilitates primary cell culture, improves the success rate of single-cell cloning and increases protein production.

Precautions:

For research use only. Not intended for clinical diagnosis or treatment.

Application Protocols

Item-specific use instructions, concentration, and composition are Not specified for this item; refer to the CoA/Spec Sheet. The following guidance reflects common literature practice for ITS/ITS+ supplements and should be validated empirically:

• Thawing: Store at −20°C (Product Data). Thaw on ice or at 2–8°C. Mix gently by inversion; avoid vigorous vortexing or foaming.
• Aliquoting: Immediately aliquot into single-use portions to avoid repeated freeze–thaw. Keep on ice during aliquoting in a biosafety cabinet.
• Working concentration: Many ITS/ITS+ products are supplied as concentrates (e.g., 100×) and used at 1× final in basal media (literature). Confirm the specific dilution for this item via CoA.
• Medium preparation: Add supplement to pre-warmed (room temperature) or cold basal medium under aseptic conditions. Gently invert to mix. If required, perform sterile filtration (0.2 µm, low-protein-binding).
• Compatibility checks: After supplementation, verify pH and osmolality. Observe for turbidity or precipitation. If combining with growth factors or albumin substitutes, add sequentially and monitor clarity.
• Culture adaptation: When moving from serum-containing conditions, gradually reduce serum while adding the supplement over several passages to support adaptation (literature best practice).
• Storage of prepared medium: Typically 2–8°C for limited periods (days), protected from light; confirm stability for this item via CoA/Spec Sheet.

Biological Roles

Literature context for typical ITS/ITS+ components (not item-specific; composition of this product is Not specified and must be verified by CoA/Spec Sheet):

• Insulin (peptide hormone): Facilitates cellular glucose uptake and metabolism; supports anabolic pathways, promoting survival and proliferation in vitro. Activates PI3K/AKT and MAPK signaling cascades (literature).
• Transferrin (iron transport glycoprotein): Delivers Fe3+ to cells via transferrin receptor–mediated endocytosis, supporting heme synthesis, mitochondrial respiration, and DNA synthesis (literature). Animal-free sources or recombinant forms are commonly used in defined media.
• Selenium (as selenite/selenate): Essential micronutrient incorporated into selenoproteins (e.g., glutathione peroxidases, thioredoxin reductases) that protect against oxidative stress and support redox homeostasis (literature).
• “Plus” components (literature variants): Ethanolamine can serve as a precursor for phosphatidylethanolamine, aiding membrane biosynthesis; some ITS+ blends may include additional defined lipids or factors.

Functional outcome (general): When added to basal media, ITS/ITS+ supplements help sustain proliferation and viability under reduced-serum or serum-free conditions, stabilize metabolic activity, and improve reproducibility by replacing undefined serum factors with defined components.

Note: Verify the exact composition, concentration, and recommended use level for this item via the CoA/Spec Sheet.

Buffer Applications

This product is not a buffering agent per se. However, practical integration with buffered media is important.

• Compatibility: Designed for use in standard cell culture media buffered with bicarbonate/CO2 or HEPES (general, literature). After addition, confirm pH (typically 7.2–7.4 for many mammalian lines) and osmolality to ensure the supplement does not perturb medium conditions.
• Order of addition: Add to cooled, pre-buffered basal medium under aseptic conditions. Mix gently to minimize foaming and protein denaturation. If compounding with other defined additives, verify compatibility and absence of precipitation.
• Filtration: If the final medium must be sterilized, use low-protein-binding 0.2 µm filters. Avoid repeated filtration passes.

Item-specific pH, buffering capacity, and ionic contributions are Not specified for this item; refer to CoA/Spec Sheet.

Green Alternatives

While “green solvent” considerations do not directly apply, the selection of an animal-free, defined supplement can contribute to more sustainable and ethical lab practices.

• Animal Free vs. animal-derived supplements:
  • Potential benefits: Reduces reliance on animal serum, improves batch-to-batch consistency, and can lower environmental and ethical impact associated with animal sourcing (general perspective).
  • Tradeoffs: Some cell lines may require optimization of growth factor and lipid content to match performance of FBS-containing media.

Comparison (general, literature; not item-specific):

• FBS supplementation (10% typical) — robust growth but high variability, animal-origin risks, and significant sourcing footprint.
• ITS/ITS+ supplementation — supports serum-free/low-serum culture with defined components; may require line-specific optimization of concentrations and additional defined additives (e.g., hormones, lipids, albumin substitutes).

For laboratories pursuing greener and more reproducible workflows, transitioning to animal-free, chemically defined media supplemented with ITS-type cocktails is a practical step, provided performance is validated per cell line.

Pharmaceutical Uses

No therapeutic/clinical use is claimed. For research use only (Product Data).

Formulation/manufacturing context (general, literature):

• Animal-free, defined supplements are often evaluated during process development for cell-based production (e.g., recombinant protein or viral vector research) to reduce variability seen with serum. Such evaluation occurs in research and preclinical process development settings.
• Benefits: Lot-to-lot consistency, reduced adventitious agent risk compared with animal serum, and improved analytical characterization of process fluids.
• Considerations: Regulatory-grade (GMP) equivalents may be required for clinical manufacturing; this product is not designated for GMP use. Transitioning from serum-containing to defined systems typically requires cell line–specific optimization.
