| Description | Sandwich ELISA quantitative detection kit for Human CD23/FCER2 in cell culture supernates, serum, plasma (heparin, EDTA) and urine. 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. 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. As part of a mapping of multiple probes to specific bands on chromosome 19 by fluorescence in situ hybridization, the FCE2 gene was assigned to 19p13.3. CD23(FCE2) is a key molecule for B-cell activation and growth. It is the low-affinity receptor for IgE. The truncated molecule can be secreted, then functioning as a potent mitogenic growth factor. Assay Range: 31.2pg/ml-2000pg/ml Sensitivity: < 10 pg/ml Crossreactivity: There is no detectable cross-rea |
