TestingforMycoplasmabyIndirectDNAStain(Hoechst33258stain)

AimDNA staining methods such as Hoechst staining techniques are quick with results available within 24 hours, which compares favorably with 4 weeks for detection by culture. However the staining of cultures directly with a DNA stain, results in a much-reduced sensitivity (~106cfu/ml). This may be improved by co-culturing the test cell line in the presence of an indicator cell line such as Vero (Prod.No. 84113001-1v1)......阅读全文

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
