Figure 1.
Expression of CD95L by transgenic islet β cells (A) and by Sertoli cells in the testis (B). Cryostat sections from a RIP–CD95Lhi pancreas or a normal testis were fixed in acetone and then stained for CD95L using a rabbit polyclonal antibody detected with an fluorescein isothiocyanate-coupled antibody to rabbit Ig. The same tissues were stained with an irrelevant rabbit polyclonal antibody (C and D).
