Total Cholesterol and Cholesteryl Ester Colorimetric Assay Kit II
產品描述：膽固醇 (Cholesterol)是所有動物生命中必不可少的分子。它涉及正常發育(normal development)和疾病(diseases)。膽固醇/膽固醇酯定量試劑盒 (Cholesterol/Cholesteryl Ester Quantitation Kit) 提供了一種使用比色法靈敏定量游離膽固醇(free cholestero)，膽固醇酯(cholesteryl esters)或兩者的簡單方法。血液中的大多數膽固醇是膽固醇酯(cholesteryl esters)的形式。這些酯(esters )可在適當條件下水解成游離膽固醇(free cholesterol)。在該測定中，游離膽固醇(free cholesterol)被膽固醇脫氫酶(cholesterol dehydrogenase)氧化以產生NADH，其與敏感探針反應，導致450nm處的強吸收。該測定可以檢測游離膽固醇(free cholesterol)或總膽固醇(total cholesterol)，這取決於酯酶是否用於水解存在的膽固醇酯。膽固醇酯 ( Cholesteryl ester )可以通過從總膽固醇（膽固醇加膽固醇酯）中減去游離膽固醇(free cholesterol )的值來確定。該試劑盒中的探針更穩定，靈敏且特異。該測定可以顯著地耐受來自各種樣品的干擾。
