Introduction
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.
Description
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.
Source
Sf9, Baculovirus cells.
