Changes in testicular lactate dehydrogenases of the rat (Rattus norvegicus) during growth and development.
1. We have quantified lactate dehydrogenase (LDH) A, B and C enzyme levels during the first twelve weeks of life in rat testes. 2. Proteins were electrophoresed under non-denaturing conditions, isoenzymes identified by activity staining and quantified by densitometry scanning. 3. LDH A declined 2-3-fold during testes growth, changing from the most to the least abundant isoenzyme form. LDH B remained fairly constant, and LDH C increased from undetectable levels at birth to become the most abundant of the three polypeptides from week 3 onwards.
