Seminal and colostral protease inhibitors on leukocytes.
For detection of protease inhibitors from cow colostrum (CTI) and bull seminal plasma (BUSI I and BUSI II) on the surface of leukocytes, immunological methods were used. An agglutination and an immunofluorescence test demonstrated components on the surface of bovine, porcine and ovine granulocytes and lymphocytes which were immunologically identical with the protease inhibitors isolated from cow colostrum and bull seminal plasma. When antisera against (CTI, BUSI and BUSI II were absorbed by bovine and porcine liver, kidney and spleen homogenate or by bovine and porcine granulocytes or lymphocytes, the immunological tests were negative.
