Aspartate Transaminase (Crude Enzyme)

       Aspartate Transaminase，中文名为天冬氨酸转氨酶，催化酸性氨基酸和α-酮酸之间的可逆反应，是转氨反应的高效催化剂。常用于医学临床上肝功能检查的指标，用来判断肝脏是否受到损害。本产品为大肠杆菌表达的天冬氨酸转氨酶，并经简单纯化获得的可以确保达到一定酶活力的粗酶液。
       由于本产品需新鲜制备，确认订购后约6个工作日才可以发货。个别情况首次制备出现问题，发货时间会顺延。
       本产品可以提供十公斤、百公斤乃至吨级的粗酶液，如有需求请联系碧云天。
       (AST) or aspartate aminotransferase, also known as AspAT/ASAT/AAT or serum glutamic oxaloacetic
transaminase(SGOT), is a pyridoxal phosphate (PLP)-dependent transaminase enzyme (EC 2.6.1.1) that was first described by Arthur Karmen and colleagues in 1954. AST catalyzes the reversible transfer of an α-amino group between aspartate and glutamate and, as such, is an important enzyme in amino acid metabolism. AST is found in the liver, heart, skeletal muscle, kidneys, brain, and red blood cells. Serum AST level, serum ALT (alanine transaminase) level, and their ratio (AST/ALT ratio) are commonly measured clinically as biomarkers for liver health. The tests are part of blood panels. This product with the indicated enzyme activity was briefly purified from engineered E.coli.
