Specifications

Product Data

• Clone Name: RFB-4
• Applications: IF, IHC
• Recommended Dilution:

  Flow Cytometry: 5 μl is the maximum amount of reagent required for 1 x 10⁶ cells. Lesser amounts of antibody may be sufficient and it is recommended that the customer determine the optimum amount of antibody for each application.
  Immunohistochemistry on Frozen Sections: Staining of frozen sections by direct fluorescence or by immuno-chemical techniques.
  Quantitative determination of peripheral B-cells (CD22⁺) in blood.
  Identification of CD22⁺ -cells in tissue sections.
  Determination of B-cell origin of lymphoid neoplasms.
  Quantitative elimination or isolation of B-cells by flow cytometry or magnet beads.

• Background: CD22 is a heterodimer consisting out of 2 glycoproteins (130 and 140 kD). The molecule is involved in signal transduction in B-cells activated via surface immunoglobulines. CD22 is in principle a B lineage antigen, that is present in the cytoplasm of progenitor B-cells and on the membrane of the majority of mature peripheral B-lymphocytes. Fur-thermore, it is strongly expressed on Hairy Cell Leukemia cells and very weakly on some other leukemias.
• Synonyms: SIGLEC2, Siglec-2, B-cell receptor CD22, Leu-14, BL-CAM
