L-Glutamine Powder for Cell Culture

L-glutamine is a commonly used amino acid supplement for mammalian, insect, and hybridoma cell culture workflows. CCM-RG-0062 is supplied in a 1 kg pack as an animal origin-free powder for users who prepare complete media, feed solutions, or controlled supplement stocks in-house. The product belongs in the cell culture reagents category and is suitable for procurement programs that require defined raw materials rather than undefined animal-derived inputs.

This material is specified with a pH range of 4.5–6.0 under the applicable test conditions, endotoxin of ≤6 EU/mL, powder form, and a 24-month shelf life when stored as directed. L-glutamine is often selected as a nitrogen and carbon source in culture systems, but its stability in aqueous solution depends on temperature, time, and formulation. For that reason, many process teams purchase powder and prepare fresh or validated stock solutions according to internal batch records. The listed pack size supports media development groups, core facilities, contract research operations, and bioprocess teams that need repeatable supplement addition without frequent small-bottle purchasing. The current list price is USD 2011.11 for the 1 kg size; volume requirements can be reviewed through request a quote.

• Supplementation of custom basal media, complete growth media, and feed formulations for research-scale and process-development cell culture.
• Preparation of defined L-glutamine stock solutions for CHO, HEK293, Vero, hybridoma, insect, and other established laboratory cell lines, subject to user validation.
• Media optimization studies where glutamine concentration is evaluated alongside glucose, amino acid balance, serum level, or chemically defined supplement packages.
• Scale-up support for users transitioning from small-volume media preparation to larger batch sizes while maintaining controlled raw-material specifications.
• Academic, biotech, biopharma, and testing laboratories that require animal origin-free cell culture supplements with documented endotoxin and shelf-life specifications.

Store CCM-RG-0062 at 2–30 °C, protected from light, in the original sealed container until use. The product ships on blue ice to support controlled transport conditions, and the receiving team should inspect the package, record arrival condition, and place the material into approved storage promptly. Use standard laboratory weighing practices to minimize moisture uptake and cross-contamination: allow the container to equilibrate if needed before opening, handle with clean dry tools, and reclose immediately after dispensing. Because L-glutamine stability is formulation-dependent once dissolved, stock solutions and supplemented media should be prepared, filtered, stored, and assigned hold times according to the user’s validated procedures.

CellCultureMedia supplies CCM-RG-0062 for research and bioprocess use with procurement-ready documentation support. Manufacturing and release controls are managed under ISO-aligned quality practices, with lot-specific records available for purchasing, QA, and process-development review. A Certificate of Analysis can be requested to confirm the applicable lot specifications, including appearance, pH range, endotoxin limit, animal origin-free classification, shelf life, and other release tests where applicable; additional documentation requests can be routed through quality documentation support. Free worldwide shipping is available on eligible orders, and packaging is selected to preserve product integrity during international transit. For recurring usage, CellCultureMedia can quote standing supply, consolidated shipment planning, and bulk pricing to help reduce procurement complexity across multiple laboratory sites.
