产品介绍
苏木素 (Hematoxylin) 和伊红 (Eosin) 联合染色简称HE染色,是病理学和组织学最常用的一种染色方法。苏木精为碱性天然染料,可使细胞核着色。细胞核内染色质的主要成分是DNA,在DNA的双螺旋结构中,两条核苷酸链上的磷酸基向外,使DNA双螺旋的外侧带负电荷,呈酸性,很容易与带正电荷的苏木精碱性染料以离子键或氢键结合而被染色。 Mayer苏木素染色液属于明矾苏木素液的一种,苏木精含量小,无氧化膜形成,对细胞核染色很清晰,不着染胞质和纤维成分,属进行性染色,故染色后不需盐酸乙醇分化,染色时间约3-5min。常用于糖原等特染、酶组化和免疫组化等染色后复染细胞核,尤其适用于在经过特殊染色后不能经酸处理时对细胞核的复染,此时染色时间较短 (通常5-10min),染完后即可进行蓝化,不必分化。在特殊染色中,Mayer苏木素染色液与天青石蓝B联合染色,使细胞核染色后不被后续的酸性染料所褪色。 使用说明: 1、根据实验具体需求和所染组织或者细胞适量染色。 2、无需盐酸乙醇分化,染色时间一般3-5min。退行性染色时需染色10-20min,进行性染色需3-5min,一般控制在10min以内。 注意事项: 1、切片脱蜡应尽量干净。系列乙醇应经常更换新液。 2、盐酸乙醇分化时间应根据切片厚薄、组织类别以及新旧而定。另外分化后自来水冲洗时间应该足够,以便彻底清洗酸。 3、冷冻切片染色时间尽量要短。 4、蓝化液常使用0.2-1%氨水或Scott促蓝液或0.1-1%碳酸锂溶液。 5、为了您的安全和健康,请穿实验服并戴一次性手套操作。 染色结果: 细胞核
