细菌的简单染色(Simple－stain)与革兰氏染色(Gram－stain)
一、目的要求1、学习细菌染色的原理和方法；2、掌握细菌的简单染色法和革兰氏染色法。二、基本原理用于生物染色的染料主要有碱性染料、酸性染料和中性染料三大类。碱性染料的离子带正电荷，能和带负电荷的物质结合。因细菌蛋白质等电点较低，当它生长于中性、碱性或弱酸性的溶液中时常带负电荷，所以通常采用碱性染料（如

SYBR－Green染料法介绍
TaqMan探针法因其良好的特异性以及可多重检测而受到实验人员的青睐，其实除了探针法外，还有很多好的实验方法也被实验人员广泛认可，这次就介绍一下另一个应用广泛的方法：SYBR Green染料法，它又是因为哪些优点获得实验人员的青睐呢？染料法原理染料法一般使用的是SYBR Green I染料，这是一种
细菌的荚膜染色(capsule－stain)
实验原理由于荚膜与染料间的亲和力弱，不易着色，通常采用负染色法染荚膜，即设法使菌体和背景着色而荚膜不着色，从而使荚膜在菌体周围呈一透明圈。由于荚膜的含水量在90%以上，故染色时一般不加热固定，以免荚膜皱缩变形。 实验器材 1.活材料 培养3-5天的胶质芽孢杆菌（Bacillus muci
