L-ASPARTIC ACID (15N) is an isotopically labeled, proteinogenic amino acid bearing the aspartic acid side chain with a terminal carboxyl group, and it contains an amino group and a carboxylic acid at the α-position. The molecule is specified as the L stereoisomer and features the 15N isotope enrichment on the amino nitrogen, which can be used to distinguish it in mass-based and NMR-based analyses while retaining the native functional group pattern of aspartate. L-ASPARTIC ACID (15N) is employed as a labeled substrate or reference in isotopic tracing, peptide and protein labeling workflows, and analytical method development where incorporation or detection of the nitrogen label is monitored.
CAT No: L-Iso-0124
