We use to investigate nuclear Tdt expression by flow cytometry with a
permeabilization protocol. We have used orthopermeafix and Perm and Fix
and they compare well. A collegue of mine is currently developing a
permeabilization protocol associating tryton and paraphormaldeyde with
excellent results in terms of detection.
