[Histonet] negative immunohistochemistry control

[cynthia haynes]

Good Morning everyone, I have a question about immuno
staining. I've been away from this type of staining
for a while and now I am doing them again on a regular
basis. Why do you run a negative control with each
run? Are you only suppose to put the normal serum on
negative control only? I've forgotten; would someone
please answer these questions for me. Thanks in
advance.
