Product Specific Information
The monoclonal antibody L26 recognizes human CD20, a transmembrane protein found on precursor and mature B lymphocytes. Expression is lost upon differentiation to plasma cells. CD20 levels are critical for evaluating malignant B lymphocytes including Non-Hodgkin’s Lymphoma, and various B-cell leukemias.
CD20 plays a role in B-cell differentiation and activation. The L26 antibody recognizes an epitope in the cytoplasmic domain, requiring tissue permeabilization for staining. Unlike antibodies targeting extracellular domains, L26 binding is not blocked by therapeutic antibodies such as Rituximab.
Applications Reported: IHC (frozen and paraffin-embedded tissue), WB, IP
Applications Tested: IHC of human FFPE tonsil with low pH antigen retrieval; ≤5 µg/mL recommended.
Antigen retrieval conditions affect staining quality and morphology. Optimized for IHC; not recommended for flow cytometry (use clone 2H7 for flow cytometry).
Purity: >90% (SDS-PAGE)
Aggregation: <10% (HPLC)
Filtration: 0.2 µm post-manufacturing filtered
Target Information
CD20 is a non-glycosylated surface phosphoprotein (33–37 kDa) expressed on mature and malignant B cells, some T cells, and follicular dendritic cells. It regulates calcium conductance, cell cycle progression, and B-cell proliferation. CD20 is associated with lipid rafts and participates in BCR signaling dynamics. Its stable membrane expression makes it a key therapeutic target for B-cell depletion in malignancies.
Diseases associated with CD20 dysfunction include Ms4a1-related common variable immune deficiency.
