Dear Ken,

no idea about "zynaxis", but doesn't sigma sell some red fluorescent
dye that binds to membranes ? There was even an add in the
last science issue (Aug 16, opposide page 863).

If I remember correctly, that is the same dye someone used in the
institute I worked before. Try medline searching for
Allen Young (Basel Institute for Immunology, Switzerland). He was
quite pleased by the stuff he used. Fluorescence was long lasting as
well.
