Fc-Gamma Receptor Binding Assays

FcγRs are members of the IgG super family and play a critical role in the function of therapeutic antibodies. Each of the different subclasses of IgG (IgG1, IgG2, IgG3 and IgG4) present different effector function profiles based on the differential binding properties to each of the FcγRs. Binding can be affected by genetic polymorphism of the receptors, as well as different glycosylation patterns in the Fc region of an antibody.

Binding Assay Development for Your Custom Antibody

BioOutsource performs FcγR binding assays for various IgG antibody isotypes or Fc fusion proteins using the Biacore T200 and 4000 systems, which are versatile, label-free systems with exceptional sensitivity. Our driven team of scientific experts partners with you to optimize the performance of FcγR binding assays and can apply this experience to novel antibody therapeutics, performing assays in a variety of different formats to meet your needs, including:

  • FcγR1/CD64
  • FcγR2a/CD32a R variant
  • FcγR2a/CD32a H variant
  • FcγR2b/CD32b
  • FcγR3a/CD16a V variant
  • FcγR3a/CD16a F variant
  • FcγR3b/CD16b

Our assays have been qualified with a range of commercially available mAbs. Contact us to find out how we can help with yours.
