TC總膽固醇檢測試劑盒 |  Total Cholesterol (TC) Colorimetric Assay Kit貨號KTB2220

CheKine™ Total Cholesterol (TC) Colorimetric Assay Kit-快速檢測血清，血漿，組織，細胞和細菌中總膽固醇(Total Cholesterol, TC)濃度

該試劑盒提供了一種簡單的方法來檢測各種生物樣品（例如血清，血漿，組織，細胞和細菌）中的總膽固醇(Total Cholesterol, TC)濃度。在測定中，酯酶(esterase)催化膽固醇酯(cholesterol esters)的水解，生成游離膽固醇（free cholesterol , FC）和游離脂肪酸（free fatty acids , FFA）。然後膽固醇氧化酶(Cholesterol oxidase)催化游離膽固醇（free cholesterol , FC）產生△4-膽固醇(△4-cholestenone)和過氧化氫(H2O2)。另外，過氧化物酶(peroxidase)可以催化H 2 O 2，4-氨基安替比林(4-aminoantipyrine)和苯酚(phenol)，形成在500nm處具有特徵吸收峰的紅色醌化合物(red quinone compounds)。樣品中的總膽固醇(Total Cholesterol, TC)與獲得的信號成比例。總膽固醇（Total Cholesterol, TC）包括游離膽固醇( free cholesterol )和膽固醇酯(cholesterol esters)。組織總膽固醇（Tissue total cholesterol, TC）是指組織中所有脂蛋白( lipoproteins )所含膽固醇( cholesterol )的總和。請使用500nm ELISA reader檢測; 若需使用分光光度計, 需更換為微量cuvette。

The kit provides a simple method for detecting TC concentration in a variety of biological samples such as serum, plasma, tissues, cells, and bacteria. In the assay, esterase catalyzes the hydrolysis of cholesterol esters to produce free cholesterol (FC) and free fatty acids (FFA). Then Cholesterol oxidase catalyzes free cholesterol (FC) to produce △4-cholestenone and H2O2. Further, H2O2, 4-aminoantipyrine and phenol can be catalyzed by peroxidase to form red quinone compounds which has a characteristic absorption peak at 500 nm. The Total Cholesterol (TC) present in the sample is proportional to the signal obtained.Total cholesterol (TC) includes free cholesterol and cholesterol esters. Tissue total cholesterol (TC) refers to the sum of cholesterol contained in all lipoproteins in the tissue.
