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.
1.It is a pharmaceutical intermediate and can also be used in biochemical research to manufacture culture agents and food additives.
2.L-Asparagine monohydrate is a naturally occurring amino acid that is not essential for humans and can be synthesized from intermediates in central metabolic pathways. Used in the synthesis of natural raw materials or pharmaceutical intermediates.
3.Microbial culture. Peptide synthesis. Assay for transaminase substrates. Mycobacterium tuberculosis culture. Biological medium preparation
