Abstract
Nine inbred strains of the rat (Rattus norvegicus) were screened for differences in electrophoretically detectable proteins. Interstrain variation was observed for 7 of 26 proteins. Three of these variants have not been described previously: leucine aminopeptidase (Lap-1), major urinary protein (Mup-1), and seminal vesicle protein (Svp-2). Genetic analysis revealed two autosomal alleles for each of these polymorphisms. The loci Lap-1, Mup-1, and Svp-2 are linked neither to one another nor to the previously described Svp-1 and Es-4 loci. Each of the nine strains can be identified now by a specific set of monogenic markers.
