Endotoxin < 1 EU/μg of the protein by LAL method.
Formulation Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.Contact us for customized product form or formulation.
Species Human
Low affinity immunoglobulin epsilon Fc receptor(CD23) is a secreted and single-pass type II membrane proteinwhich is also exists as a soluble excreted form. There are two forms of CD23: CD23a and CD23b. CD23a ispresent on follicular B cells, whereas CD23b requires IL-4 to be expressed on T-cells, monocytes, Langerhanscells, eosinophils, and macrophages. Unlike many of the antibody receptors, CD23/FCER2 is a C-type lectin. It isfound on mature B cells, activated macrophages, eosinophils, follicular dendritic cells, and platelets. In flowcytometry, CD23/FCER2 is helpful in the differentiation of chronic lymphocytic leukemia (CD23-positive) frommantle cell leukemia (CD23-negative). CD23/FCER2 can also be demonstrated in germinal centre B-cells usingimmunohistochemistry, but it is not present in the resting cells of the surrounding mantle zone. CD23/FCER2has essential roles in the regulation of IgE production and in the differentiation of B-cells (it is a B-cell-specificantigen).
