RESUMO
The Epstein-Barr virus/C3d receptor (CR2) of human B lymphocytes was purified to homogeneity from Raji cells by immunoaffinity chromatography. The average yield of the 145-kilodalton receptor was 400 pmol (50 micrograms) per 10(10) cells, representing an approximate 75% recovery. The isolated 145-kilodalton protein was antigenically and functionally intact as it reacted with several anti-CR2 monoclonal antibodies and bound purified Epstein-Barr virus and C3d,g. These findings with the purified molecule provide an unequivocal demonstration of the dual receptor functions of this protein.
