This recombinant Human IgG1 Fc protein is produced in and purified from HEK293 cells. It is great to use as a negative control in binding assays such as ELISA and flow cytometry that use antibodies containing the human IgG1 Fc domain as a constant region.



Recombinant fusion proteins consisting of the extracellular domain of immunoregulatory proteins and the constant (Fc) domain of immunoglobulin G1 (IgG1) represent a growing class of human therapeutics. Chimeric protein of Human antigen-targeting variable domain and Human IgG-Fc domain can be purified using protein A chromatography. Our product, E1011, is the Human IgG1 Fc domain control protein, purified using protein A-agarose (GE, cat. # 17-5438). MW ~55 kDa.
