Four novel cell lines, ATCC #HB-8862 through ATCC #HB-8865 produce monoclonal antibody to human plasma prekallikrein. At least three of the antibodies also recognize plasma kallikrein, specifically the heavy chain thereof, and kallikrein-Cl-inhibitor complex; at least one of these three antibodies recognizes kallikrein-alpha2-macroglobulin complex and kallikrein-antithrombin III complex. The antibodies do not cross-react with tissue kallikrein. The hybridomas are formed by fusing spleen cells from immunized BALB/c AnSkh mice with SP2/O-Agl4 myeloma cells. Diagnostic and biochemical uses of the monoclonal antibodies are provided. |
