      Background CD21 is also called the complement receptor 2 type (CR2) and EB virus receptor, is a member of the complement activation regulators family.CD21 is mainly distributed in mature B cells, dendritic cells in lymphoid follicles, and part of the T cells. The functions of CD21 include promoting proliferation of B cell, mediating transformation of EBV to B cells and participating in immune memory. It is mainly used for diagnosis of follicular cell tumors and study of regulation of immune complement activation.

      Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human tonsil tissue labeling CD21 Monoclonal Antibody with E-PA-3201 at dilution of 1:500. Heat induced epitope retrieval was performed by boiling the tissue sections in citrate buffer(PH6.0)for 20 minutes. Incubation with the primary antibody was performed for overnight at 4℃ followed by keeping at room temperature for 15mins. HRP conjugated Anti-Mouse secondary antibody was applied for 30 minutes at room temperature followed by DAB as chromogen, then counterstain with haematoxylin.
