title: Monoclonal antibody to alkaline phosphatase from the intestinal mucosa of the harp seal, Phoca groenlandica.
abstract: 1. Hybridoma secreting a monoclonal antibody APP.1 to the harp seal alkaline phosphatase (A1Ph) was obtained by fusing murine myeloma Sp 2/0 cells with the splenocytes of BALB/c mice immunized with purified isozyme K. 2. The antibody has no effect on the enzyme activity and shows a high affinity for harp seal A1Ph (KD = 8.5 x 10(-10) M). The antibody has similar affinities for the AlPh of harp seal, fur seal, common seal and deer. 3. The antibody APP.1 was coupled to Sepharose and employed in chromatographic purification of the harp seal intestinal AlPh. Alkaline phosphatase isolated on this immunosorbent has a spec. act. of 20,800 units per mg of protein. 4. The antibody-enzyme complex gives an excellent immunocytochemical labeling of tissue sections, cell cultures and smears.
