[Incorporation of radioactive leucine into lizard epididymis proteins. Study during the sexual cycle and after injection of testosterone to untreated or castrated animals].

Lizard epididymis activity during the reproductive cycle and after testosterone administration results in a marked increase of radioactive leucine incorporation in vivo and in vitro. The electrophoretic distribution of soluble proteins shows different peaks of radioactivity. Comparison between histological response and pattern of electrophoresis suggests that one of these peaks may correspond to an activity of secretion.
