Polymorphism of lactate dehydrogenase B subunit in rat erythrocytes.

A new electrophoretic variant of the lactate dehydrogenase B subunit was found in the erythrocytes of the COP strain of the rat. The location of the band after the electrophoresis suggested a product of the structural gene for the B subunit. Two alleles that regulated the high amount (Ldh-2 a )or the low amount (Ldh-2 b )of the B subunit were found and segregated in Mendelian fashion. The activity was regulated by the closely linked (<1 cM) regulatory gene Ldr-1.
