The C2 antibody reacts with the transferrin receptor CD71, a disulfide-linked homodimer of 95- kDa subunits. CD71 mediates one of the cellular mechanisms for iron uptake, and its expression is regulated according to the cell's iron requirements. It is expressed at high levels on developing erythroid cells, and it is upregulated after mitogenic activation of B or T lymphocytes. C2 mAb selectivity inhibits some types of T- and B-cell activation by down-regulation of transferrin receptor expression, but it does not block binding of transferrin. Although the isotype of C2 mAb was originally reported to be Rat IgG2a, further investigations have demonstrated that it is Rat IgG1, κ.
