MTT法简介
MTT法是一种检测细胞存活和生长的方法。MTT为黄色化合物,是一种接受氢离子的染料,可作用于活细胞线粒体中的呼吸链,在琥珀酸脱氢酶和细胞色素C的作用下,外源性MT还原为水不溶性的蓝紫色结晶甲瓒( Formazan)并沉积在细胞中,而死细胞无此功能。二甲基亚砜(DMSO)能溶解细胞中的甲瓒,用酶联免疫
MTT实验心得
MTT实验是检测细胞活力的实验方法，由于细胞活力与细胞数呈正相关，因此也常常用来检测细胞的增殖情况。MTT的原理：活细胞有琥珀酸脱氢酶，将MTT还原成棕褐色沉淀。由于一般介绍园子里已经很多，笔者将自己的心得按照实验流程与大家交流交流。1、培养好细胞点板。养细胞没啥好说的，如果不知道细胞如何养，那就看
