Dear List-Members



First I want to thank the people who kindly answered to my question about acid-resistant haematoxylin. I have a question about inmunohistochemistry. I have to make a inmuno to detect ATPase but then I would like to make another staining like PAS or H&E. Could these "counterstainins" affect the inmuno reaction or even cuould the inmuno response be lost or masked?. I want to distinguish to kinds of cells, both of then are positive to PAS but only one is positive to ATPase, I would like to show the two in the same picture. Any help or comentary would be appreciated



thanks in advance



José Luis
