Localization of Total Proteins and Lactate Dehydrogenase in Hamster Epididymis

The concentration of total protein measured by photocolorimetric methodology and reported as units per 100 mg of tissue decreased from the initial segment to the cauda epididymidis of the Golden hamster, being significant the numeric difference observed between these two regions. This observation wa...
