We wish to do a double immunostain for CD34 and active caspase 3 on
paraformaldehyde fixed mouse tissues. The cd34 primary is rat monoclonal
anti cd34 The caspase 3 primary is a rabbit polyclonal antibody.
We would like to use the Dako Envision G/2 kit for double staining, however
this kit is for mouse or rabbit primaries only. When we do a single stain
for cd34, we use a Rabbit anti Rat IgG as a linking antibody between the
primary and secondary antibody (Dako Envision plus kit for rabbit
primaries) and this works well on our tissues in our experience.
My question is: Can I add this linking antibody step to the method and
still use the Envision G/2 kit?
Does anyone have any experience with this sort of thing or any different
ideas on doing double staining using these particular antibodies?
All ideas and comment appreciated as always.
