Project Introduction

苏木精- 伊红stain法 ( hematoxylin-eosin staining ) , 简称HEstain法 , 石蜡切片技术里常用ofstain法之一 . 苏木精 染液for碱性, mainly使cell核内ofstain质with胞质内ofnucleic acid着紫蓝色;伊红for 酸性染料 , mainly使cell质and cell外基质 中of成分着红色.HEstain法istissue学, 胚胎学 , 病理学教学with科研中most基本, usingmost广泛of技术方法.

Sample Requirements

1, 样品可for新鲜tissue, cell爬片, 4%多聚甲醛固定oftissue/cell, 蜡块或OCT包埋包埋剂包好ofcell/tissue, as well asalready做好切片oftissue.

2, Sample Type不一样, 价格have所差异. (need进行前process, such as需包埋, 切片, 则需收取前process费用)


FAQ

    Q1, 切片in脱蜡后出现大量白色斑点

    (1) 烤 (烘) 片温度太低, 玻片in脱蜡前没have充分烤 (烘) 干 - 先用无水乙醇去除玻片上of水分, 然后重新用二甲苯进行脱蜡process.

    (2) 切片in二甲苯停留时间不足 或停留时间过久 - 切片需退回到二甲苯Operating Steps, 使其停留时间相对长些, 或更换二甲苯, 进行重新stain.

    Q2, cell核stain暗淡, 即苏木精stain太淡

    (1) 切片in苏木精stain液停留时间太短

    (2) 苏木精stain液过度氧化, 失去stain能力, 不能再继续using

    (3) 分化步骤时间过长. such as果is骨tissuecell核暗淡, 则多数is由于脱钙过度造成.

    改善方法: 切片需重新stain, such as果tissuein固定液固定时间过长, cell核stain能力将减弱, 需增加其in苏木精stain液of时间, 或用一些方法增加tissueof嗜碱性, 以改善cell核of着色.

    Q3, cell核过染, 即苏木精颜色过深, 甚至苏木精颜色of分布占据了cell质of位置

    (1)  切片in苏木精stain液停留时间过长

    (2)  切片太厚

    (3)  分化步骤时间过短

    改善方式: such as果切片不is因for太厚, 对切片进行重新stain, 对于stainand分化时间做出适当地调整; such as果确定is由于切片太厚导致cell核过染, 则need重新切片.

    Q4, cell核呈红, 棕色改变

    苏木精stain液过度氧化and切片in苏木精染液stain后返蓝不足- 每timesstain之前检查苏木精stain液ofstain能力, 发现氧化过度及时更换. 其times, 可用流水, 温水或弱碱性溶液such as稀氨水, 0.2%碳酸氢钠etc., in苏木精stain后, 给切片足够of蓝化时间.
