[The 4th complement factor (C4) and t haplotypes in wild mice].

Abstract

Five different lines of tailless mice bearing different t recessive haplotypes (tAn, tMo, tRa, tLa and tQu) have been established in our laboratory and maintained in combination with the brachury chromosome (T). These t haplotypes were derived from widely separated Chilean wild mouse populations. The immunoelectrophoretic typing for Ss and Slp isotypic variants of C4 showed that all lines had the Ss-High. Slp-negative phenotype suggesting that the t haplotypes might be associated with similar S regions of the major histocompatibility system of the mouse.
