ABO blood grouping of semen from mixed body fluids with monoclonal antibody to tissue-specific epitopes on seminal ABO blood group substance.
1991
Practical methods were developed for ABO blood grouping of semen from mixed body fluids. An monoclonal antibody (P6-5H) which recognizes a tissuespecific epitope on a seminal ABO blood group substance (α2-seminoglycoprotein) was used as a solid phase antibody for selective capture of the seminal ABO blood group substance. ABO blood group epitopes of secretor and non-secretor semen were detected in dilutions of 8 x 103−3.2 x 104 and 8 x 103-fold, respectively, by sandwich ELISA. ABO blood group epitopes were also detected in dilutions up to 4 x 103-fold, irrespective of secretor status, by the sandwich absorption-elution test.
