Specifications

L-Aspartic acid (Asp) is one of the 20 proteinogenic amino acids as building block for protein. Although a non-essential amino acid in mammals, it is a precursor to several other amino acids including four essential amino A3880-01acids (Met, Thr, Ile and Lys). Aspartate is a metabolite in the urea cycle, participates in gluconeogenesis and transports reducing equivalents between the cytosol and the mitochondria via the malate-aspartate shuttle. Aspartate also stimulates NMDA receptors (not as strongly as glutamate) and hence serves as an excitatory neurotransmitter in the brain and is an excitotoxin.
Catalog #	A3881
	The Aspartate Assay Kit provides a simple, convenient assay to measure aspartate in a variety of samples. In the assay, aspartate is converted to pyruvate which is oxidized with the conversion of a probe into a highly colored (570nm) and fluorescent (Ex/Em 535/587nm) species proportional to the amount of aspartate in samples. Aspartate can be quantified in the range between 0.1–10nmoles/well (2-200uM).
