47 POLYMORPHIC MICROSATELLITE LOCI IN DIFFERENT INBRED RAT STRAINS

62 microsatellite markers were analyzed for polymorphisms between 9 in bred rat strains, including 2 congenic strains. 47 of them were polymo rphic between at least two rat strains tested. Two alleles were detect ed at 12 and mt,re than 2 at further 35 loci. The highest genetic dive rsity between 2 non-related strains was 89% of all loci tested between BB/OK as well as BBDP and SHR/Mol rats and the lowest was found betwe en BB/OK and NEDH/Mol (47%). No differences were found between the con genic strains BB.1A and LEW.1BB and their background strains BB/OK and LEW.
