???????Aspartate Transaminase，中文名為天冬氨酸轉(zhuǎn)氨酶，催化酸性氨基酸和α-酮酸之間的可逆反應(yīng)，是轉(zhuǎn)氨反應(yīng)的高效催化劑。常用于醫(yī)學(xué)臨床上肝功能檢查的指標(biāo)，用來(lái)判斷肝臟是否受到損害。本產(chǎn)品為大腸桿菌表達(dá)的天冬氨酸轉(zhuǎn)氨酶，并經(jīng)簡(jiǎn)單純化獲得的可以確保達(dá)到一定酶活力的粗酶液。
???????由于本產(chǎn)品需新鮮制備，確認(rèn)訂購(gòu)后約6個(gè)工作日才可以發(fā)貨。個(gè)別情況首次制備出現(xiàn)問(wèn)題，發(fā)貨時(shí)間會(huì)順延。
???????本產(chǎn)品可以提供十公斤、百公斤乃至噸級(jí)的粗酶液，如有需求請(qǐng)聯(lián)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.
