Equine marker genes: Polymorphism for plasminogen

Abstract
Polymorphism for 2 autosomal alleles of equine plasminogen, PLG1 and PLG2, was demonstrated in plasma by isoelectric focusing and immunofixation, with a goat anti-human plasminogen antibody. The frequency of PLG2 was 0.16 in 150 Standardbreds, 0.20 in 96 Thoroughbreds and 0.39 in 32 Shetland ponies. No evidence for linkage of PLG with any of 13 marker loci was found.
