  • Synthesis and Application of a Cationic

    SDS-polyacrylamide gel electrophoresis revealed that the apparent molecular weights of the polypeptide subunits were 34,000 and 19,000, respectively. Both anionic and cationic antigens in cell-free K99 extracts adhered to sheep erythrocytes after 90 min at 4 degrees C, but the cationic antigen eluted after a further 1 h at 37 degrees C.
