Medchemexpress LLC L-Asparagine-d3 hydrate | 2483831-59-8 | 153.15 | 1 MG
L-Asparagine-d3 hydrate is the deuterium labeled L-Asparagine. It is an essential amino acid for leukemic cells and a substrate for L-Asparaginase. L-Asparaginase is a potent anti-leukemic enzyme that promotes asparagine (Asn) and glutamine (Gln) depletion and inhibits protein biosynthesis in lymphoblasts. Removal of L-asparagine from plasma by L-Asparaginase results in inhibition of RNA and DNA synthesis and subsequent apoptosis. L-Asparaginase has cell-killing ability in vitro and in vivo, and selectively inhibits the growth of cancer cells with low asparagine synthetase (AASNS) expression. L-Asparagine can be used as a biomarker and sensor for the study of childhood acute lymphoblastic leukemia.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
