RE: [Histonet] negative immuno histochemistry control

From:"Edwards, R.E."

For polyclonal antibodies use species specific(rabbit,goatetcetc) normal serum, or  pre-immune if available: for  mouse monoclonals use the  specific isotypic e.g.  IgG2a; simply omitting the  primary  antibody  or  replacing it  with  diluent  alone  is  no  control.

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

Cynthia Haynes H.T.
