Fc-Gamma Receptor Binding Assay Services

Fcγ receptors are a family of glycoproteins expressed on a variety of immune cells and have affinity for the Fc region of immunoglobulin G (IgG). The receptor family includes several members: FcγRI (CD64), FcγRIIa/b/c (CD32a/b/c) and FcγRIIIa/b (CD16a/b). Each of them has a characteristic preference for binding to the IgG isotype and can transduce activation signals (for example, FcyRI, IIa, IIIa) or inhibitory signals (for example, FcyRIIb). FcγR has been shown to be very important in regulating the efficacy of therapeutic antibodies through FcγR-mediated phagocytosis, cytokine production, antibody-dependent cell-mediated cytotoxicity (ADCC) and antibody-dependent cell-mediated phagocytosis (ADCP).

Creative Biolabs uses the Biacore T200 instrument to provide FcR binding assays to obtain detailed kinetic information about antibody-receptor interactions. Two different measurement settings are established in opposite coupling directions to select the best measurement for your research.

Custom antibody binding assay development

Creative Biolabs uses Biacore T200 and 4000 systems to perform FcγR binding assays for various IgG antibody isotypes or Fc fusion proteins. This system is a universal label-free system with excellent sensitivity. Our team of scientific experts will work with you to optimize the performance of the FcγR binding assay, and apply this experience to novel antibody therapies to perform assays in a variety of different formats to meet your needs, including:
