产品介绍
固定的目的是防止细菌的腐蚀和组织的自溶,保存细胞固有的物质,能凝固或沉淀细胞内或组织液,糖原等,使细胞或组织基本上保持与生活时的物质一样,使组织硬化,便于切块。固定液主要分为醛类固定液、汞类固定液、醇类固定液、氧化剂类固定液、苦味酸盐类固定液等,较常用的是醛类中的福尔马林、醇类中的乙醇。 戊二醛固定液 (4%, 电镜专用) 由戊二醛、磷酸盐、去离子水等组成,pH7.2~7.4,该固定液对细胞核、细胞浆的细微结构固定效果好,经常用于电镜标本的固定。 保存: 2~8℃,避光,12个月 使用方法 1、取新鲜标本,立即入戊二醛固定液(4%,电镜专用)中固定,稍大标本应适当延长固定时间。 2、送检或 4℃保存。 注意事项 1、戊二醛固定液有一定腐蚀性,请在通风较好的环境下小心操作,避免吸入。 2、组织取材的厚度不同, 固定时间也不同。常规活检组织比较适合的厚 2~4mm,一般不超过 6mm。对组织恰当的选材有利于固定液的渗透。 3、固定液的容量应足够,一般固定液与组织块的体积比率应大于 10:1。如果容积不够大,可以在固定期间更换 1~3 次固定液。 4、温度对固定的影响很明显,提高温度可以加速固定作用,但本固定液最好不要提高温度。 5、取出新鲜组织后,应及时固定。无法及时固定时,应保存于生理盐水中及时送检。 6、为了您的安全和健康,请穿实验服并戴一次性手套操作。
