Anti-CD23 Antibody

The CD23 antigen, also known as FcεRII or the low-affinity immunoglobulin E receptor, is a type II transmembrane protein expressed on mature B lymphocytes, activated macrophages, eosinophils, and certain epithelial cells. It plays a central role in IgE-mediated immune regulation, allergen processing, and B-cell signaling, making it a frequent target in allergy, asthma, and lymphoma research. This mouse monoclonal reagent from Antibodies.com is supplied as an unconjugated IgG preparation in a 100 µl volume, suitable for western blot and immunohistochemistry workflows on human, rat, and mouse samples. Researchers commonly apply it to investigate CD23 expression patterns in B-cell chronic lymphocytic leukemia, allergic airway inflammation models, and lymphoid tissue sections. The unconjugated format allows flexible pairing with secondary antibodies labeled with HRP, fluorophores, or biotin, depending on the detection chemistry required. Store refrigerated and protect from light in single-use aliquots to preserve binding activity across repeated experiments.
