The genetic monitoring of inbred strains of rat through biochemical approach

A genetic monitoring technique to examine the genetic authenticity of inbred strains of rat was developed and established through biochemical approaches. Four inbred strains, F344/N, LEW /Sea, SHR /Crj and WKYO, were monitored genetically using electrophoresis techniques such as polyacrylamide gel eletrophoresis(PAGE) or cellulose acetate membrane electrophoresis. Results from the present study are as follows; It is very efficient and useful to identify inbred strains of rat for the detection of gene loci of biochemical markers as the genetic monitoring technique. Twenty-three biochemical markers were examined for their gene loci to apply to genetic monitoring, but only a few markers are enough to monitor genetically rat strains for the most case. For genetic monitoring of gene loci which are variable in each substrain, a detection method of major histocompatibility complex (MHC) must be applied together.
