Recombinant Human CD23, Sf9

Low affinity immunoglobulin epsilon Fc receptor isoform a, BLAST-2, CD23, CD23A, CLEC4J, FCE2, IGEBF, C-type lectin domain family 4 member J, Immunoglobulin E-binding factor, Lymphocyte IgE receptor.

FCER2, or Fc epsilon RII, is a receptor for IgE with low affinity, which is critical to regulation of IgE levels. IgE is an antibody isotype that attached to allergy and resistance to parasites. FCER2 is a C-type lectin, contrary to many of the receptors for antibodies. FCER2 is located on activated macrophages, mature B cells, follicular dendritic cells, platelets and eosinophils.

CD23 produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 283 amino acids (48-321a.a.) and having a molecular mass of 32.0kDa. 
CD23 is expressed with a 6 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
