Biosystems Aspartate Aminotransferase

Biosystems Aspartate Aminotransferase

PRINCIPLE OF THE METHOD: Aspartate aminotransferase (AST or GOT) catalyzes the transfer of the amino group from
aspartate to 2-oxoglutarate, forming oxalacetate and glutamate. The catalytic concentration isdetermined from the rate of decrease of NADH, measured at 340 nm, by means of the malate
dehydrogenase (MDH) coupled reaction1,2,3
Aspartate + 2 – Oxoglutarate Oxalacetate + Glutamate Oxalacetate + NADH + H+ Malate + NAD+



WARNING: H302: Harmful if swallowed. EUH031: Contact with acids liberates toxic gas.

Call a POISON CENTER or doctor/physician if you feel unwell. P330: Rinse mouth.

For further warnings and precautions, see the product safety data sheet (SDS).
