although the sample size was small , the greater degree of discrimination among the vwd plasmas tested with bd2-cc9 ( compared with the other two antibodies [ ca3-ae4 , cc6-bg10 ] ) suggests that this antibody may recognize conformational epitopes that reflect the degree of multimeric polymerization of the vwf molecule rather than simply recognize a decreased number of antigenic sites in a basic subunit .
