蛋白酶K(凍干粉)
- 別名:Proteinase K;Endopeptidase K; Prok; Protease K;39450-01-6
- 編碼:EBY0027I
- 級(jí)別:≥30 Units/mg protein
- 簡(jiǎn)介:蛋白酶K是一種枯草蛋白酶類的高活性蛋白酶,用于生物樣品中蛋白質(zhì)的一般降解。蛋白酶K是一種切割活性較廣的絲氨酸蛋白酶。它切割脂族氨基酸和芳香族氨基酸的羧基端肽鍵。此酶經(jīng)純化去除了RNA酶和DNA酶活性。由于蛋白酶K在尿素和SDS中穩(wěn)定,還具有降解天然蛋白質(zhì)的能力。

產(chǎn)品介紹
蛋白酶K是一種枯草蛋白酶類的高活性蛋白酶,用于生物樣品中蛋白質(zhì)的一般降解。蛋白酶K是一種切割活性較廣的絲氨酸蛋白酶。它切割脂族氨基酸和芳香族氨基酸的羧基端肽鍵。此酶經(jīng)純化去除了RNA酶和DNA酶活性。由于蛋白酶K在尿素和SDS中穩(wěn)定,還具有降解天然蛋白質(zhì)的能力。
蛋白酶K用途
- 基因診斷試劑盒
- 基因組DNA提取試劑盒
- RNA提取試劑盒中去除DNA和RNA制備中的核酸酶
- 提取組織中非蛋白成份降解含有蛋白質(zhì)的雜質(zhì)-譬如DNA疫苗和肝素的制備
- 制備脈沖電泳的染色體DNA
- 蛋白質(zhì)印跡
- 蛋白酶K的一般工作濃度50-100ug/ml
