Abstract
The purpose of this study is to investigate the immunological difference between intestinal, liver, kidney, bone, placental and serum alkaline phosphatase (ALPs) in cattle. Kidney, bone and placental ALPs were purified from each tissue by gel filtration and ion-exchange chromatographies, and intestinal, liver, and placental ALPs were obtained from a commercial source. The antibody to each tissue ALP was prepared by immunizing rabbits and tested by double immunodiffusion analysis in cross reactivities. The results indicated that the bovine tissue ALPs are divided into four groups in antigenicity, that is, intestinal, bone, liver and kidney-placental ALPs. The fetus, calf and cow sera contained bone ALP, and calf and cow sera also contained kidney or placental ALP, but all of the sera did not contain intestinal and liver ALP.
