Abstract

Starch gel electrophoresis of lactate dehydrogenase (LDH) from Hyla crucifer tissues showed a typical five banded pattern with fast, anodally migrating isozymes predominating in heart tissue and slower migrating isozymes predominating in skeletal muscle. A population survey revealed electrophoretic variability in apparently the skeletal muscle monomer (M) for LDH, indicative of a relatively high degree of polymorphism for this locus in H. crucifer. No variants for the heart monomer were detected, and most M variants were apparently homozygotes. More extensive population studies are needed to corroborate these findings.
