Description: The monoclonal antibody L26 recognizes human CD20, a two transmembrane spanning protein found on precursor and mature B lymphocytes. Expression is lost upon differentiation to plasma cells. The levels of CD20 are critical in evaluating malignant B lymphocytes including Non-Hodgkin's Lymphoma, and Acute B cell, Chronic Lymphocytic and Hairy-Cell Leukemias. CD20 plays a role in B cell differentiation and activation. The structure of the protein shows a small extracellular loop with the carboxy and amino termini in the cytoplasmic compartment. The L26 antibody recognizes an epitope in the cytoplasmic domain and therefore requires permeabilization of the tissue for staining applications. Unlike many anti-CD20 antibodies that recognize the extracellular domain, the epitope recognized by L26 will not be blocked by therapeutic antibodies to CD20, like Rituximab.Applications Reported: This L26 antibody has been reported for use in immunohistochemical staining of frozen tissue sections, and immunohistochemical staining of formalin-fixed paraffin embedded tissue sections.Applications Tested: This L26 antibody has been tested by immunohistochemical staining of human FFPE tonsil with low pH antigen retrieval (cat. 00-4955) and can be used at less than or equal to 10 μg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. It has been reported that the L26 antibody when used without antigen retrieval will detect a subpopulationof CD20-positive cells. The L26 antibody can be used with high pH antigen retrieval, although the quality of the staining and cell morphology is not optimal. This product has been optimized for use in immunohistochemistry. We do not recommend its use in flow cytometry. For flow cytometry applications, please refer to clone 2H7, cat. 11-0209.Excitation: 488 nm; Emission: 519 nm; Laser: Blue Laser.Filtration: 0.2μm post-manufacturing filtered.
