Fluorescent quenching

[Rocky Baker]

I have used p-phenylenediamine added to buffered glycerol as described in 
J. Immunological Methods 43(1981)349-350 with good success in standard 
epifluorescence microscopy.  It allowed 2 minute exposures of fluorescent 
antibody preps (using FITC conjugates) with little fading.  I have also 
heard of using n-propyl gallate but I have no specifics on that one.
