Alanine transaminase (ALT) is a transaminase enzyme. It is also called alanine aminotransferase (ALAT) and was formerly called serum glutamate-pyruvate transaminase (SGPT) or serum glutamic-pyruvic transaminase (SGPT). ALT is found in plasma and in various body tissues, but is most common in the liver. It catalyzes the two parts of the alanine cycle. Serum ALT level, serum AST (aspartate transaminase) level, and their ratio (AST/ALT ratio) are commonly measured clinically as biomarkers for liver health. The tests are part of blood panels.
ALT, Recombinant (Human)
Sterile liquid formulation.
Alanine Aminotransferase Human Recombinant produced in E. coli is a homodimer, nonglycosylated, polypeptide chain containing 495a.a and having a molecular mass of 54,479 Dalton. The amino acid sequence is the same as that of native form of human liver ALT. The ALT is purified by proprietary chromatographic techniques.
Greater than 95.0% as determined by (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
AAT1 although stable at 10°C for 5 days, should be stored desiccated below -18°C. Please prevent freeze-thaw cycles.
The protein was dialyzed against 40mM sodium acetate buffer (pH 5.5), 1mM DTT,1mM EDTA, 5mM 2-oxoglutarate and 0.1mM pyridoxal-5'-phosphate.
