Lactate dehydrogenase and malate dehydrogenase isozyme patterns in tissues of temperature-acclimated goldfish (Carassius auratus L.)

Abstract

1.1. The lactate dehydrogenase and malate dehydrogenase isozyme patterns from goldfish (Carassius auratus L.) tissues were examined by starch gel electrophoresis and immunoprecipitation.2.2. Electrophoretic analyses reveal no detectable qualitative or quantitative alterations in the isozyme patterns due to the effects of temperature acclimation at 5, 15 and 25°C.3.3. The only variations of LDH* isozyme patterns observed were those attributable to genetic polymorphism and to different ratios of red and white skeletal muscle fibres.
