Activity of B6dom1 and H-Y peptides in CTL sensitization assays. 51Cr-labeled T2Db targets that had been preincubated with various concentrations of H-Y or B6dom1 synthetic peptides were incubated for 4 hours with polyclonal anti–H-Y or anti-B6dom1 CTLs (E:T ratio 50:1). One representative experiment of four is shown.
