L-Alanyl-L-cystine
L-Alanyl-L-cystine (CAS No. 115888-13-6) is a white crystalline dipeptide composed of alanine and cystine, with a molecular weight of 382.5 g/mol and a purity of 99% min. It is commonly used in cell culture media and pharmaceutical development, especially in serum-free environments where a reliable cystine source is essential.
By providing a more stable and soluble form of cystine, this compound helps support antioxidant mechanisms and promotes cellular growth under nutrient-limited conditions. It should be stored at 2–8 °C in sealed containers to preserve quality. It is available in 25 kg fibre drums, with a monthly output of up to 1 ton to ensure stable supply for ongoing research and production needs.
