(S)-2-Aminosuccinic acid 4-amide; (S)-(+)-2-Aminosuccinamic acid; L-Aspartic acid 4-amide; L-Asn-OH·H2O

L-Asparagine is used in cell culture media and is a component of MEM non-essential amino acids solution. L-Asparagine has been shown to enhance ornithine decarboxylase activity in cultured human colon adenocarcinoma Caco-2 cells and in cultured IEC-6 intestinal epithelial cells. Spore germination in Bacillus subtilis has been increased in the presence of L-asparagine. L-Asparagine, a proteinogenic amino acid, from non-animal source is used in biomanufacturing cell culture systems for the production of therapeutic recombinant proteins and monoclonal antibodies. It has also been used as a component of LHC basal media for the culture of human airway epithelial cells.
