The monoclonal antibody S19, expressed by Deposit HB12144, ATCC, effectively agglutinates a sperm surface glycoprotein, SAGA-1 protein. The mAB finds utility as a binding agent in a spermicide, showing a high degree of effectiveness in binding potential sperm. The protein bound, identified as SAGA-1, is the immunogen in a contraceptive vaccine, as well as the standard for determining antibody titer upon vaccination. The monoclonal antibody can also be used as a diagnostic to determine the presence, and amount, of sperm in a variety of samples. |
