Apexbio Technology LLC L-Alanyl-L-Glutamine 39537-23-0 25g

L-Alanyl-L-glutamine (CAS 39537-23-0) is a stable water-soluble dipeptide consisting of L-glutamine and L-alanine Following oral or enteral administration it is hydrolyzed in the gastrointestinal tract locally supporting maintenance of the intestinal mucosal barrier and modulating barrier function This activity results in reduced bacterial translocation and a lowered risk of infection and associated complications such as diarrhea and malabsorption The dipeptide enhances intestinal uptake of L-glutamine compared to free L-glutamine and has been shown to influence antioxidant capacity attenuate inflammatory responses and regulate heat shock protein expression under catabolic conditions L-Alanyl-L-glutamine serves as a versatile tool for studies of gut physiology nutrient absorption and cellular stress responses in biomedical research

ILEX LIFE SCIENCES LLC CMRL 1066 P04-84600 6 X 500 ML

PAN-Biotech CMRL 1066 Cell Culture Medium, w/o: L-Glutamine, w/o: Phenol red, w: 2.2 g/L NaHCO3 (6 x 500 ml). BICARBONATE: With 2.2 g/L Sodium Bicarbonate. GLUCOSE: With glucose. GLUTAMINE: Without glutamine. PHENOL RED: Without Phenol Red. HEPES: Without HEPES. SODIUM PYRUVATE: Without sodium pyruvate. STERILE: Yes. STORAGE TEMP: +2-8°C. MANUFACTURER: PAN-Biotech GmbH. COUNTRY OF ORIGIN: Germany. INTRO: CMRL 1066 Medium is a chemically-defined medium, developed in the 1950s by Connaught Medical Research Laboratories for serum-free culture of L-strain cells, as a highly modified and less complex version of Medium 199 (M199). It has been used to maintain monolayer growth of permanent cell lines for years without protein supplementation. Initially developed for serum-free conditions, it can be supplemented with serum and used to support the growth of many cell types. COMPOSITION: CMRL-1066 is a nucleoside-rich, vitamin-rich medium that contains no proteins, lipids, or growth factors.

ILEX LIFE SCIENCES LLC STABLE GLUTAMINE 200MM 50ML

PAN-Biotech Stable Glutamine 200 mM (100x), L-alanyl-L-glutamine dipeptide, 50 ml. MANUFACTURER: PAN-Biotech GmbH (Germany). INTRO: Stable Glutamine 200 mM solution contains L-alanyl-L-glutamine dipeptide, a more stable alternative to L-Glutamine, which is an essential amino acid required by all mammalian cells but is more unstable in cell culture solutions than other amino acids. It is suitable for both adherent and suspension culture of mammalian cells with no adaptation needed. ADVANTAGES: Minimizes toxic ammonia build-up: Stable glutamine does not spontaneously break down to form ammonia. Instead, cells cleave the dipeptide bond to release L-Glutamine as needed. Improves cell viability/growth: cultures with lower levels of ammonia show improved cell viability. Remains stable across a wide temperature range. APPLICATION: 10 ml of stable glutamine solution is sufficient for up to 1 L of medium. COMPOSITION: L-Alanyl-L-Glutamine: 43,440.00 mg/L; Sodium Chloride: 8,500.00 mg/L.
