Product introduction
产品介绍: 醇溶性伊红染液(Alcohol Soluble Eosin Y Stainin Solution)是一种酸性生物染料,主要使细胞质和细胞外基质成分着红色,尤其是线粒体,分泌颗粒和胶原,可以区分细胞内不同的细胞器以及不同的结缔组织。本品可以用于组织切片或培养细胞的染色,染色后细胞浆呈粉红色或红色。本品可以和免疫荧光染色和免疫组化染色配合使用,一方面可以在本品染色后进行免疫荧光染料或其他染料的染色,另一方面也可以在免疫组化染色后再进行伊红复染。染色过程需要优化,着色情况与组织或细胞种类有关,也随其生活周期及病理变化而改变 。 使用方法: 1.样品处理:a)对于石蜡切片:二甲苯中脱蜡5-10min,换用新鲜的二甲苯再脱蜡5-10min,无水乙醇5min,90%乙酸2min,70%乙醇2min,蒸馏水2min;b)对于冰冻切片:蒸馏水2min;c)对于培养细胞:用4%多聚甲醛固定10min以上,蒸馏水洗涤2min,换用新鲜的蒸馏水再洗涤2min;2.伊红染色:本品染色2min(本品为工作液,可直接使用),根据染色结果和要求调整时间;用蒸馏水洗去多余染料,此时,如果需要直接观察,可以用70%乙醇洗涤两次;如需脱水,透明后封片案后续步骤进行,70%乙醇洗涤后仍可按照后续步骤进行脱水,透明和封片处理。注:如果用于免疫组化等染色后的复染,可以参考上述步骤在其它染色完成后直接进行伊红染色。3.进行其它染色:如果进行免疫荧光染色,伊红染色液染色后,蒸馏水洗去多余染料,70%乙醇洗涤两次,每次2min,再用PBS或生理盐水,TBS,TBST等用于免疫染色或荧光染料染色的溶液浸泡5min,然后就可以进行免疫荧光染色或其他染色。 使用范围: 适用于一般生物学及医学研究
