产品介绍
新赛美生物的蛋白酶和磷酸酶抑制剂混合液(Protease and PhosphataseInhibitor Cocktail) 是经优化好的多种蛋白酶和磷酸酶抑制剂的混合物组成的,仅用一种溶液即可方便地完 成在抽提和纯化蛋白时,能够有效防止蛋白被内源性的蛋白酶和磷酸酶的降解。成分含 有 Aprotinin,Bestatin,Leupetin,Pepstatin,PMSF,NaF,Sodium Orthovanadate,Sodium Pyrophosphate 等多种蛋白酶和磷酸酶家族的抑制剂,主要抑制氨基肽酶、半胱氨酸和 丝氨酸蛋白酶、丝氨酸/苏氨酸和酪氨酸蛋白酶和磷酸酶、蛋白酪氨酸磷酸酶、碱性磷 酸酶、酸性磷酸酶等,用于蛋白纯化,蛋白免疫印迹, 免疫共沉淀,免疫荧光,免疫组 织化学,激酶测定等研究。
操作步骤
在室温下溶解含有蛋白酶和磷酸酶抑制剂混合液,混匀之后,根据实验体系的需求, 按照 1:100 的比率将抑制剂混合液加入到样品溶液中(如组织抽提物或细胞裂解物)。
保存条件
-20 ℃保存,冰袋运输,至少 1 年有效;
注意事项
1. 蛋白酶和磷酸酶抑制剂严重损害呼吸道粘膜、眼睛及皮肤,吸入、吞进或通过皮肤吸收 后有致命危险; 2. 不同样品中含有的蛋白酶和磷酸酶的量及种类不同,可根据具体实验调整加入抑制剂混 合液的量,如加入 2 倍,3 倍等量,才能有效抑制内源性蛋白酶和磷酸酶的作用 3. 为了您的安全和健康,请穿实验服并戴防护手套操作
