I cannot recommend you this G/2 kit as this is sequential as well as
multi-species based. A home-brew solution is more appropriate here:
Rt CD34 + Rb casp-3 (cocktail)
Goat anti-rat/HRP (mouse absorbed)* + goat anti-rabbit/AP polymer **
Develop AP activity in red (Dako LPR)
Develop HRP activity in brown (DAB+ from any source)
* = see Jackson or Rockland
** = see LabVision
Lots of success with staining!

Subject: [Histonet] Double immunostaining with a rabbit and rat
We wish to do a double immunostain for CD34 and active caspase 3 on
paraformaldehyde fixed mouse tissues. The cd34 primary is rat
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,
this kit is for mouse or rabbit primaries only. When we do a single
for cd34, we use a Rabbit anti Rat IgG as a linking antibody between
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 exper
