title: Properties of alkaline phosphatase of the human dental pulp.
abstract: Enzymatic and immunological properties of alkaline phosphatase [ALP; orthophosphoric monoester phosphohydrolase, alkaline optimum, EC 3.1.3.1.] in the human dental pulp were investigated. In inhibition and thermal inactivation studies, dental pulp ALP showed properties of universal-type ALP (kidney/bone/liver type). Dental pulp ALP cross-reacted with polyclonal and monoclonal antibodies against purified swine-kidney ALP, and with monoclonal antibody against ALP of human osteoblast-like cells in the same manner as ALPs of human bone and kidney. The sodium dodecyl sulfate-gel electrophoretic pattern showed a 140,000-Mr native protein band. These data suggest that dental pulp ALP can be classified as a universal-type ALP having antigenic determinants common to ALP of the kidney and bone.
