Activity and electrophoretic forms of alkaline and acid phosphatases in the reproductive system of laying hen.
The activity of both enzymes was measured in the extracts of all parts of the reproductive system of the hen. Very high activity of alkaline phosphatase was found in the follicle membranes and very low values in the oviduct. The values of the activity of acid phosphatase are similar in various parts of the oviduct and ovary. Only in the contents of the follicle and in the yolk the activity was near zero. The electrophorograms of alkaline and acid phosphatases in the ovary and the oviduct show similar phenotypes as in the blood. It seems that acid phosphatase does not play any topical role in the functions of the reproductive system. Very high activity of alkaline phosphatase, particularly in the membrane of the ovarian follicles, confirms the suggestion that this enzyme has an active role in the transport of yolk material from the blood into the follicle during its growth.
