感谢倪老师的解答~这两天在看你提供的这篇文献以及相关的参考文献,仍然没有得到确定的答案(ps由于磁珠 ...
我认为有99%的可能是CK7,你看啊,仔细阅读你加亮的这句话:
Isolated cholangiocytes (95–100% pure by CK-7 immunohistochemistry) were obtained by immunoaffinity separation24,28,29 with a monoclonal antibody, rat IgG2a (provided by Dr R Faris, Providence, RI, USA), against an antigen expressed by cholangiocytes
重点就在加粗的这些单词和红色的单词上,它这个IgG2a肯定不是同型对照的抗体,而是针对胆管上皮细胞的某个抗原,但为什么不直接说出抗原名称,我就不知道,但作者分离后用CK7免疫组化来验证其纯度,这就证实这个针对的antigen极有可能就是CK7。否则为什么用CK7验证纯度?你说呢
