Dear Anne,

I assume the glutaraldehyde tissue has been processed and embedded in 
paraffin. Following removal of paraffin and any pretreatment to unmask the 
antigen, you can block autofluorescence or change the color by treating 
the sections with 0.05% sodium borohydride prepared in PBS for 30 minutes. 
After the borohydride treatment, carefully wash the slides with multiple 
changes of PBS for thirty minutes. I would also use a good quality silane 
treated slide for maximum tissue adhesion.
A comment of caution: sodium borohydride is poisonous. Be extremely 
careful with the powder.

I used this method in a double label fluorescence project a few years ago 
with excellent success.

[Histonet] DIF tissue in GLUT

Dear John and other knowledgeable Histonetters and Gurus of the trade....

Renal bx tissue core has been placed in Gluteraldehyde/Trumps EM
fixative by mistake (we all make mistakes) - we now need to do DIF
Does anyone out there have a method for this?
