A recombinant fragment (within amino acids 100-300) of human Complement receptor 2/CD21 protein was used as the immunogen for the recombinant CR2 antibody.
Recognizes a protein of 140kDa, which is identified as the complement receptor 2(CR2)/CD21. This protein is expressed strongly on mature B cells, follicular dendritic cells and weakly on immature thymocytes and T lymphocytes. In B-cell ontogeny, CD21 app
