Comparison of the steroid-induced, intestinal, and hepatic isoenzymes of alkaline phosphatase in the dog

Abstract
SUMMARY: The steroid-induced, intestinal, and hepatic isoenzymes of canine alkaline phosphatase (alp) were compared, usmg antibodies against the steroid-induced alp isoenzyme, heat inactivation, phenylalanine inhibition, prednisolone inhibition, and Michaelis constant determinations. The results indicate that the steroid-induced and intestinal alp isoenzymes are similar and indicate that the steroid-induced isoenzyme might be a product of the same gene that controls the intestinal isoenzyme.
