Fc Characterization

Antibodies and antibody-based therapeutics have the potential to elicit immune functions through binding to Fc-γ receptors (FcγR) on immune cells or fixing complement. According to ICH Q6B and EMA mAb guidelines, the Fc region of a mAb needs to be characterized for IND and BLA submissions. Working with a passionate, savvy scientific team helps to streamline this part of the process.

Assay Development to Meet Your Needs

For the most common isotypes of therapeutic mAbs, BioOutsource offers pre-developed, pre-qualified assays for analysis of Fc binding to FcγR and C1q. The assays enable faster, more economical characterization of a molecule’s Fc regions with solutions that are ready to implement immediately for early phase testing.

Some of these technologies include:

  • FcγR by Biacore (Full Panel)
  • FcRn  by Biacore (Human, Rat, Mouse, or Cynomologous Monkey)
  • C1q by Biacore
  • C1q by ELISABioOutsource Fc Characterization Services

With extensive experience in Fc characterization, our team can work to customize a solution to meet the unique requirements of each product. And with flexible global capacity, including a large facility in Glasgow, UK, services are available where you need them most.
