    Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

    Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.

    Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.

    We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.

    In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.

    We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.

    Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

    Please check that this product meets your needs before purchasing. If you have any questions, special requirements or concerns, please send us an inquiry and/or contact our Support team ahead of purchase.

IHC-P 1/250. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

Target

  • Function

    Receptor for complement C3Dd, for the Epstein-Barr virus on human B-cells and T-cells and for HNRPU. Participates in B lymphocytes activation.
  • Tissue specificity

    Mature B-lymphocytes, T-lymphocytes, pharyngeal epithelial cells, astrocytes and follicular dendritic cells of the spleen.
  • Involvement in disease

    Genetic variations in CR2 are associated with susceptibility to systemic lupus erythematosus type 9 (SLEB9) [MIM:610927]. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a complex genetic basis. SLE is an inflammatory, and often febrile multisystemic disorder of connective tissue characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is thought to represent a failure of the regulatory mechanisms of the autoimmune system.
  • Sequence similarities

    Belongs to the receptors of complement activation (RCA) family.
    Contains 15 Sushi (CCP/SCR) domains.
  • Cellular localization

    Membrane.
  • Target information above from: UniProt accession P20023 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010
    Nucleic Acids Res. 38:D142-D148 (2010) .

      Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - HRP Anti-CD21 antibody [EP3093] (ab202354)

      IHC image of CD21 staining in a section of formalin-fixed paraffin-embedded normal human tonsil tissue*, performed on a Leica BONDTM. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab202354, 1/250 dilution, for 15 mins at room temperature. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset negative control image is taken from an identical assay without primary antibody.

      For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

      Developed using the ECL technique.

      Performed under reducing conditions.

      Predicted band size: 113 kDa
      Observed band size: 155 kDa
      why is the actual band size different from the predicted?


      Exposure time: 8 minutes


      This blot was produced using a 3-8% Tris Acetate gel under the TA buffer system. The gel was run at 150V for 60 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% milk before being incubated with ab202354 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.
