Industrial Applications of Glycyl-L-glutamine monohydrate
| Industry | Application | Process |
|---|---|---|
| Biopharmaceuticals | Cell culture supplement; replaces glutamine to improve culture stability and cell viability | Dissolved directly into serum-free or low-serum media at typical concentrations of 2–4 mM; used under standard culture conditions (37°C, 5% CO₂) |
| Life Science Research | Maintains cellular metabolic homeostasis and reduces ammonia accumulation in vitro | Used as a stable glutamine precursor; added in batch or fed-batch mode during long-term culture, high-density passaging, or post-thaw recovery |
| Vaccine Production | Supports vaccine vector production in mammalian cell lines (e.g., CHO, Vero), enhancing recombinant protein expression and product quality | Integrated into perfusion or intensified batch processes; co-regulates metabolic flux with glucose and amino acids to reduce ammonia byproduct concentration |
Manufacturing Quality Control of Glycyl-L-glutamine monohydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by reversed-phase HPLC with UV detection at 210 nm, using a calibrated standard curve. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV against reference standards or threshold limits. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine total water content. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue after ignition at 700-800 C to assess inorganic ash content. |
