Recombinant Human Fc Protein, IgG1 (CAT#: CB-P446-K) Datasheet

Product Type
The Fc (Fragment, crystallizable) region, located in the base of the Y-shape antibody and composed of two heavy chains with two or three constant domains depending on the class of the antibody, binds to a specific class of Fc receptors and other immune molecules, such as complement proteins, to induce an appropriate immune response for a given antigen. The Fc region bears two highly conserved N-glycosylation sites, one on each heavy chain. The N-glycans attached to this site are predominantly core-fucosylated diantennary structures of the complex type. In addition, small amounts of these N-glycans also bear bisecting GlcNAc and α-2,6-linked sialic acid residues.

The recombinant human IgG1 Fc protein was produced in HEK 293 cells and purified by protein A.
