CD23 Antibody - Protein Microarray Validated clone FCER2/3592 recognizes CD23, a type II transmembrane glycoprotein encoded by the FCER2 gene on chromosome 19p13.3. CD23 is also known as Low affinity immunoglobulin epsilon Fc receptor or Fc epsilon receptor II and belongs to the C-type lectin family. It functions as the low affinity receptor for IgE and plays an important role in regulating IgE mediated immune responses and B cell biology. CD23 is primarily expressed on mature B lymphocytes, with additional expression reported in certain activated immune cell populations.
Structurally, CD23 contains a short N-terminal cytoplasmic domain, a single transmembrane segment, and a large extracellular C-type lectin-like domain responsible for IgE binding. CD23 can exist in both membrane bound and soluble forms, the latter generated by proteolytic cleavage. Through interactions with IgE and CD21, CD23 participates in antigen presentation, modulation of IgE synthesis, and regulation of B cell activation and differentiation. Subcellular localization is predominantly membranous, often accompanied by variable cytoplasmic staining depending on cellular activation state.
In normal tissues, CD23 expression is most prominent in secondary lymphoid organs such as tonsil, lymph node, and spleen. Within these tissues, CD23 is characteristically expressed by follicular B cells in germinal centers and mantle zones, where it contributes to humoral immune regulation. The staining pattern typically highlights follicular architecture, with strong membranous labeling in B cell rich regions and limited staining in T cell predominant interfollicular areas. CD23 antibody is widely used in research settings to study B cell subsets, germinal center reactions, and immune activation.
Protein microarray validation demonstrates high specificity of clone FCER2/3592 for its intended target across a broad panel of human proteins. Such validation supports its utility for detecting CD23 expression in research applications focused on immunology, allergy related mechanisms, and lymphoid tissue biology.
Optimal dilution of the CD23 antibody should be determined by the researcher.
1. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
A recombinant human FCER2/CD23 protein fragment within amino acids 48-321 was used as the immunogen for the CD23 antibody protein microarray validated clone FCER2/3592.
Store the CD23 antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
