HEPES Buffer Solution (1M)

Volume: 100 ml Storage: +2°C to +8°C Sterility: Sterile-filtered HEPES Buffer Solution (1 M), also known as N-2-hydroxyethylpiperazine-N-2-ethanesulfonic acid, is a zwitterionic organic buffering agent widely used in cell culture media. It is designed to maintain stable pH conditions in the physiological range of 6.7 to 8.6, supporting optimal cellular function during in vitro applications. Application and Benefits HEPES provides reliable buffering capacity in cell culture systems, particularly when cells are handled outside a CO₂ incubator. The addition of 10–25 mM HEPES to culture media offers enhanced pH stability during extended manipulation periods, helping to maintain consistent experimental conditions. This buffer is membrane-impermeable, has minimal interference with biochemical reactions, and demonstrates strong chemical and enzymatic stability. These properties make it suitable for a wide range of cell culture and biochemical applications. Formulation and Usage The solution is supplied as a 1 M concentrate prepared in cell culture–grade water and is sterile-filtered for use in contamination-sensitive environments. It can be diluted to the desired working concentration depending on application requirements. Store at +2°C to +8°C and handle under aseptic conditions to preserve product integrity. For research use only. Not for use in diagnostic or therapeutic procedures. Not for use in humans or animals.

Stable Glutamin (200mM), L-Alanyl-L-Glutamine Solution

Volume: 100 ml Storage: ≤ –15°C Sterility: Sterile-filtered Stable Glutamine Solution (L-Alanyl-L-Glutamine, 200 mM) is a highly stable dipeptide form of L-glutamine designed as a direct replacement for conventional L-glutamine in cell culture media. L-glutamine is an essential amino acid and a major energy source for cultured cells, playing a critical role in cell growth, metabolism, and protein synthesis. Application and Benefits In standard liquid media, L-glutamine degrades relatively quickly at 37°C, leading to the formation of toxic byproducts such as ammonium ions that can negatively affect cell viability and experimental outcomes. Stable glutamine overcomes this limitation by providing a non-degrading dipeptide form that remains intact in culture conditions. Cells enzymatically cleave the dipeptide bond to release L-glutamine as needed, ensuring a continuous fresh supply while preventing the accumulation of harmful waste products. This makes the solution particularly advantageous for long-term cell cultures and high-density growth systems. Formulation and Usage The L-Alanyl-L-Glutamine solution is prepared in cell culture–grade water at a concentration of 200 mM and is sterile-filtered for contamination-sensitive applications. It can be diluted directly into complete media according to experimental requirements. Store at ≤ –15°C and avoid repeated freeze-thaw cycles to maintain product stability. For research use only. Not for use in diagnostic or therapeutic procedures. Not for use in humans or animals.
