Cat#:PA-2905F;Product Name:Rabbit Anti-Human Fc fragment of IgE, low affinity II, receptor for (CD23) Antibody;Synonym:CD23; FCE2; CD23A; IGEBF; CLEC4J; low affinity immunoglobulin epsilon Fc receptor; BLAST-2; CD23 antigen; fc-epsilon-RII; lymphocyte IgE receptor; immunoglobulin E-binding factor; C-type lectin domain family 4, member J;Background:CD23, also known as Fc epsilon RII, or FcεRII, is the "low-affinity" receptor for IgE, an antibody isotype involved in allergy and resistance to parasites, and is important in regulation of IgE levels. Unlike many of the antibody receptors, CD23 is a C-type lectin. It is found on mature B cells, activated macrophages, eosinophils, follicular dendritic cells, and platelets. There are two forms of CD23: CD23a and CD23b. CD23a is present on follicular B cells, whereas CD23b requires IL-4 to be expressed on T-cells, monocytes, Langerhans cells, eosinophils, and macrophages.;Description:Rabbit Anti-Human Fc fragment of IgE, low affinity II, receptor for (CD23) Monoclonal Antibody;Formulation:Liquid Solution;Host Species:Rabbit;Species Reactivity:Human;Clone#:SP34;Isotype:N/A;Application:IHC;Storage:Store antibody products at 2-8°C.
