| Product Name | L-Glutamine Cell Culture Supplement (CAS 56-85-9) |
| Catalog No. | RERE-0022 |
| Description | L-Glutamine is a basic amino acid that cells in culture cannot do without: it drives energy generation and underpins protein and nucleic acid synthesis, and cultures deprived of it grow poorly or die off. Beyond nutrition it feeds the glutathione pathway, strengthening the culture's antioxidant capacity, and helps buffer intracellular pH during metabolism. The compound is supplied as a white crystalline powder that dissolves readily into complete media, and it is equally at home in nutritional formulations and general biomedical research work. Note that the molecule degrades relatively fast at elevated temperature or at extreme pH, so storage conditions matter for maintaining full activity. |
| Intended Use | Fortification of basal culture media for growing and dividing cells; support of energy metabolism and macromolecular synthesis; a precursor for glutathione-linked antioxidant studies; general nutritional and biomedical research. |
| Principle / Technology | As a conditionally essential amino acid, L-Glutamine feeds the TCA cycle and nitrogen metabolism. Cultures consume it continuously, and without replenishment growth stalls and viability falls, so periodic supplementation keeps the medium nutritionally complete. |
| Sample Type | White crystalline powder for dissolution into complete culture medium or buffer. |
| Performance Range / Specifications | Cell-culture-grade purity; supplies energy and nitrogen for biosynthesis; supports glutathione-mediated antioxidant defence; helps balance intracellular pH during metabolism. |
| Specificity | CAS number 56-85-9; molecular formula C5H10N2O3; molecular weight 146.15; purity 98%; appearance white crystalline powder. |
| Reaction Conditions / Protocol | Dissolve the required amount into complete culture medium, filter or rely on medium sterility as appropriate to the workflow, and supplement cultures according to the formulation being followed. |
| Components / Formulation | One bottle of L-Glutamine powder (100 g). |
| Storage Conditions | Store at room temperature; a shelf life of 2 years applies. |
| Shelf Life | 2 years from receipt when stored as recommended. |
| Package Specifications | 100 g per bottle |
| Product Form | White crystalline powder. |
| Quality Control | Released at 98% purity against the stated molecular identity; appearance is checked as white crystalline powder. |
| Key Features | - 98% cell-culture-grade purity with full molecular identity - Feeds energy metabolism, protein and nucleic acid synthesis - Supports the glutathione antioxidant pathway - Room-temperature storage with a 2-year shelf life |
| Purity | 98% |
| Activity / Unit Definition | Functional contribution is expressed through culture growth support rather than a numeric activity unit. |
| Molecular Weight | 146.15 |
| Source / Origin | Synthesised cell-culture-grade amino acid; no biological origin. |
| Shipping Conditions | Shipped at room temperature. |
| Expiration Date / Stability | Degrades faster when exposed to heat or strongly acidic or alkaline conditions; keep dry, sealed and away from temperature extremes. |
| Regulatory / Compliance | For research use only. |
| Compatibility | Suitable for essentially any adherent or suspension mammalian culture format that uses glutamine-supplemented basal media. |
| Recommended Buffer System | Supplied undissolved; prepare working solutions in the medium or buffer of choice. |
| Application Notes / Precautions | Avoid prolonged exposure to heat and strong acid or alkali, which accelerate decomposition; prepare solutions fresh where possible and store the bottle tightly closed in a dry place. |
| Batch-to-Batch Consistency | Lot consistency is controlled by release on purity and identity; each lot carries its release record. |
| Model Type | Cell culture medium supplement |
| Starting Material / Tissue Site | Synthetic L-Glutamine, 98% purity |
| Delivery Standard | 100 g bottle |
| Turnaround Time | dispatch is arranged at order confirmation. |
| Readouts / Downstream Assays | Culture growth rate and viability in supplemented versus unsupplemented media. |
For research use only, not for clinical use.
