1)做免疫组化的片子最好不要同时做HE染色,因为那样会掩盖阳性着色的结果;而且用苏木素复染细胞核也是淡染,若要在免疫组化的片子上观察形态学的改变,除非有非常典型的表现,一般是有很大的难度的。
2)你是培养的细胞做免疫组化吗?如果是的话,那就每个样本只有一张片子吧?唯一的办法是进行免疫双染,同时做CD34和AFP(甲胎蛋白)。我觉得后者阳性便可以或多或少的获得向肝细胞分化的证据。
3)用HE染色来识别造血干细胞向肝细胞分化,也就是说要看到肝细胞的典型形态学改变后才可以下结论。问题是:早期的肝细胞仅凭形细胞态学观察并不能很容易的被识别。病理大夫看组织切片,重要的是看其组织学结构,对肝细胞也是这样。如果单拿出来一个细胞,还是培养的细胞,染色后真的不容易区分。所以我觉得你设计的用HE染色来确定早期细胞向哪个方向分化不是很有说服力。
4)如果是切片,也就是说每个样本可以有多张切片,那可以在连续切片上分别染CD34和AFP,拍照时选择相同视野,也有一定说服力。但是还是不如双染法更可靠。
5)用双染最大的问题在于:这两者都表达在胞浆中,染色容易相互覆盖。所以在双染的方法选择上你还要再考虑一下,可不可以用免疫荧光双染?这样也很有说服力的
有没有朋友使用碧云天的细胞衰老β-半乳糖苷酶染色试剂盒做过细胞衰老,本人小白,求相关细胞处理的过程及数据分析方法。贴壁细胞六孔板需要接种多少,染色后怎样计数进行数据处理。谢谢啦!
的抗体不容易染色,哪为同仁有这方面的经验?另外基因公司卖的cellsignalingtechnology的抗体要1875元,而中山公司卖的这个抗体只有800多,其中差距在哪里?请赐教
