I'm just about to begin injecting mouse brains with a GFP-tagged lentivirus. After sacrificing, the brains will be sectioned on a microtome and immunohistochemistry will be performed on the free floating sections. I was wondering if doing DAB staining affects the GFP fluorescence at all? I will want to see co-localisation of different markers with GFP-positive cells so would it be better to stain the cells using fluorescently tagged secondary antibodies or would the GFP expression still be present after doing the DAB reaction?
