Sodium borohydride is an excellent agent for reducing background
fluorescence in several different preps and applications. The exact way
you would use it will depend on precisely what type of labeling you are
trying to accomplish. For immunocytochemistry of isolated neurons we rinse
the fix off the cultures with PBS then deionized water, apply 0.5-1% NaBH4
at room temp for 1-2 minutes (dissolve NaBH4 in deionized water, NOT PBS);
rinse in water, then in PBS. The blocking agent is applied next, then the
primary antibody. Good Luck.
