Abstract

These studies were carried out to survey the genetic contamination of six inbred mice (A, BALB/c, C3H, C57BL/6, CBA and KK) produced and supplied from the conventional breeding unit for improving the quality of mice as experimental animal. We examined alleles of five loci (Akp-1, Car-2, Hbb, Es-1 and Trf) by the use of biochemical markers with celluose acetate electrophoresis. As the results of test, BALB/c, A, C3H, C57BL/6, CBA and KK showed standard alleles in Akp-1, Car-2 and Hbb. But Es-1 of A and C57BL/6 and Trf of A, C3H, C57BL/6 and CBA did allelic divergence in loci. These results suggest that the colonies of A, C3H, C57BL/6 and CBA were genetically contaminated. Therefore, we recommend to eliminate the genetically contaminated mice thoroughly, to check on genetic monitoring regularly and to consider a counterpaln for improving the quality control as soon as possible.
