Fc receptors play a key role in immune cell activation through antibody stimulation, they can specifically bind to the Fc region of the immunoglobulins. In addition, FcR has become a key participant in the pathogenesis of several important autoimmune diseases. Targeting Fc receptors as a therapeutic method for the treatment of inflammatory diseases and cancers. For example, blocking/neutralizing activated receptors (Antibody), Inhibitory FcγRIIB (agonist) participation. Therefore, high-quality Fc receptors are indispensable.

ACROBiosystems has launched the FcR proteins with the SUMO fusion tag and HAS fusion tag, which can be used in immunization and antibody screening to accelerating the development of specific antibody drugs.
