Monoclonal antibody against human bone alkaline phosphatase.
A monoclonal antibody which reacts preferentially with human bone alkaline phosphatase (AP) has been developed using human osteosarcoma bone AP as an immunogen. The antibody with the highest selectivity shows about three- and a-half fold greater binding to bone than to liver AP. The selectivity was confirmed using mixtures of authentic samples of the bone and liver isoenzymes. Its selectivity was also shown by measurements of bone AP in sera from patients with either bone or liver diseases. Such a selective antibody could lead to the development of a monoclonal antibody highly specific for bone AP which can be used for a more sensitive approach for quantitative analysis of the isoenzyme.
