Kuo, San Kao, Ching-Feng Weng and Sin-Che Lee (1999) In order
to more completely understand the complete basis for the multiple LDH
isozymes in lizards, seven species of Taiwanese lizards belonging to 4
families and 7 genera were sampled. Starch gel electrophoretic patterns
of lizard LDH isozymes from brain, eye, heart, liver, muscle, and
testis were analyzed. Like all other vertebrates, lizards possess the 2
fundamental LDH loci—A and B. A 3rd locus, LDH-C, was detected only in
testes of Hemidactylus frenatus,
Eumeces elegans, and Mabuya longicaudata. This
testisspecific product, designated according to tissue-specific
expression exhibited, a faster anodal migration than did the other LDH
isozymes. These findings suggest that the testis-specific LDH isozyme
was derived from ancestor amniote LDH-A.
Key words: Lizard,
