SKU: orb2276514

Description

CD20 antibody validated for immunohistochemistry on 76 different Normal Tissues

Images & Validation

• Tested Applications: IHC
• Dilution Range: 1:100-1:200
• Reactivity: Human
• Application Notes:
  Positive Control: Tonsil or appendix: A strong, predominantly membranous staining of the mantle zone B-cells, the germinal centre B- cells and the interfollicular B-cells is required, while all other cells should stain negative. Negative Control: Tonsil or appendix: A large fraction of the interfollicular lymphocytes and all epithelial cells must not show any staining. Cellular Localization: Cell Surface Protocol Recommendations: Manual Protocol: Freshly cut sections should be used (less than 10 days between cutting and staining). Heat-induced antigen retrieval for 5 minutes in an autoclave at 121°C in pH 7.8 Target Retrieval Solution buffer. Apply the antibody at a dilution of 1:150 at 37°C for 60 minutes. Visualization of bound antibody by the EnVision Kit (Dako, Agilent) according to the manufacturer’s directions.

Alternative Names

APY; ATOPY; B-lymphocyte cell-surface antigen B1; Bp35; Fc epsilon receptor I beta chain; Fc Fragment of IgE high affinity I receptor for beta polypeptide; FCER1B; High affinity immunoglobulin epsilon receptor subunit beta; IgE Fc receptor subunit beta; IGEL; IGER; IGHER; LEU16; Leukocyte surface antigen Leu-16; Ly44; MS4A1; MS4A3

Strong CD20 staining of a germinal centre in the appendix mucosa while epithelial cells are completely negative.

The thymus contains a relatively low fraction of CD20 positive B-lymphocytes.

In the tonsil, many lymphocytes stain positive while the surface epithelium is CD20 negative.
