Anti-Fc fragment of IgG receptor Ia antibodies are available from several suppliers. In humans, this protein is encoded by the gene FCGR1A. The protein may also be known as CD64A, FCRI, CD64, IGFR1, high affinity immunoglobulin gamma Fc receptor I, and Fc fragment of IgG, high affinity Ia, receptor (CD64). The expected protein mass is 42.6 kDa, but there are 2 reported isoforms. Variants of this antigen may also be found in other species, including canine, porcine and rat.
