- Extra Details:
- The CD23 antigen is the low affinity IgE Fc receptor, which is a 49kD protein with 38 and 28kD fragments.1 It is expressed on most mature, conventional B cells (but not on peritoneal CD5+ B cells), and can also be found on the surface of T cells, macrophages and platelets.1-6 It is distinct from the high affinity IgE receptors found on basophils and mast cells, which mediate allergic reactions. The low affinity receptors are thought to play a role in isotype specific immunoregulation.3 The regulation of CD23 surface expression appears to be integral with the complex IgE system, which involves interactions of cells, cytokines, antibodies and regulatory factors.2-6 CD23 has been described as a “membrane bound cytokine," in that the soluble cleavage products of CD23 are themselves able to act as cytokines in vitro.6 Applications: Suitable for use in Flow Cytometry, FLISA and Immunohistochemistry. Other applications not tested. Recommended Dilution: Immunohistochemistry: frozen Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4°C in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: PE conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
