Fc Fusion Protein Production

Creative BioMart has become leading manufacturer of protein products for life science research. One of our specialties is to develop unique immunoglobulin based chimeric fusion proteins utilizing cellular and molecular biology techniques.

What is Fc Fusion Protein?

Due to the nature of the antibody IgG-Fc, Fc fusion proteins play significant role in dimerization, in vivo half-life, receptor activation and ligand affinity. Considering many receptors are only bio-functional as dimeric form, a Fc fusion receptor protein can mimic the activated form and enhance its affinity to ligand. Besides, Fc domain also simplifies its detection (by western blot or ELISA) & purification (by protein A or protein G affinity chromatography) steps. Mammalian cell-specific glycosylation from the Fc domain of the protein also makes itself suitable for in vivo studies. If desired, the Fc domain can be cleaved by treatment with protease.

Application of Fc Fusion Protein in Biopharmaceutical Industry

In the biopharmaceutical industry, as novel biological entities with potential for therapeutic activities, Fc-fusion proteins have become a class of biologic medicines for human disease. In some cases, these fusions are used as standalone therapeutic modalities; in others, they have provided alternatives when therapeutic monoclonal antibodies (mAbs) or other medications have failed to provide successful therapeutic results.
