[Histonet] T Cell and B Cell Markers on Lymph Node Touch Preps

[Woodward, Denise]

In my experience, CD20 does not work in canine or feline tissues. Try
CD79a instead. I can't comment on the use of touch preps. With FFPE,
Dako TRS pH9 for 20 minutes works great.

Subject: [Histonet] T Cell and B Cell Markers on Lymph Node Touch Preps

Hello,

            Does anyone have experience with performing
Immunocytochemistry (CD3, CD20) on touch preps of canine and feline
lymph nodes, particularly the following:

 

Fixation: What reagent(s), what temperature, how long, immediately or
wait until air dried, storage post fixing

 

Antigen Retrieval: If formalin is part of the fixative, is there a
general rule for HIER on ICC specimens that relates to HIER on paraffin
sections of lymph nodes for CD3 and CD20?

 

Thank you so very much.
