Recombinant Human Fc fragment of IgG, low affinity IIb, receptor (CD32), His-tagged

Specification :
| Description : FCGR2B is a low affinity receptor for the Fc region of immunoglobulin gamma complexes. The protein is involved in the phagocytosis of immune complexes and in the regulation of antibody production by B-cells. Variations in this gene may increase susceptibilty to systemic lupus erythematosus (SLE). Several transcript variants encoding different have been found for this gene. Recombinant human FCGR2B protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques. | Source : E.coli | Species : Human | Tag : His-tag | Form : Liquid.
