Product details

Human AST ELISA Kit (Aspartate Aminotransferase) ab263881 is a rapid single-wash 90-min ELISA kit to measure Human AST in cell culture extracts, tissue extracts, cell culture supernatant, serum and plasma. This SimpleStep ELISA® sensitivity is 43 pg/mL.

How the assay works
Human AST SimpleStep ELISA® employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.

Assay Specificity
This kit is designed for the quantification of human AST. The standard protein in this kit is full length human AST. Native signal was detected in serum, plasma (citrate), plasma (EDTA), plasma (heparin), cell culture supernatant, cell extract and tissue extract sample types. Saliva, urine, milk, and CSF samples have not been tested with this kit.

Target data

Biosynthesis of L-glutamate from L-aspartate or L-cysteine (PubMed : 21900944). Important regulator of levels of glutamate, the major excitatory neurotransmitter of the vertebrate central nervous system. Acts as a scavenger of glutamate in brain neuroprotection. The aspartate aminotransferase activity is involved in hepatic glucose synthesis during development and in adipocyte glyceroneogenesis. Using L-cysteine as substrate, regulates levels of mercaptopyruvate, an important source of hydrogen sulfide. Mercaptopyruvate is converted into H(2)S via the action of 3-mercaptopyruvate sulfurtransferase (3MST). Hydrogen sulfide is an important synaptic modulator and neuroprotectant in the brain. In addition, catalyzes (2S)-2-aminobutanoate, a by-product in the cysteine biosynthesis pathway (PubMed : 27827456).
