in this study we found that by painting the tails of mice with the hapten trinitrochlorobenzene ( tncb ) , sensitization was induced in certain mouse strains ( balb/c , a/j , and cba -- haplotypes h-2d , h-2a , h-2k , respectively ) , but tolerance resulted from painting the tails of other strains ( c57bl/6 , c57bl/10 , and ab.y -- haplotype h-2b ) .
