      Product Information
      PresentationPurified from mouse ascitic fluid. The antibody is supplied in 25 mM Tris-HCl buffer, 0.4 M NaCl, pH 8.0, containing 0.2% bovine serum albumin and 0.1% sodium azide. The characteristics of each lot are tested by electrophoresis and flow cytometry.
      ApplicationThis Anti-Human B cells CD19 Antibody, clone FMC63 is validated for use in FC, IF for the detection of CD19.
      Key Applications
      • Flow Cytometry
      • Immunofluorescence
      Application NotesThis antibody is useful for enumerating normal B lymphocytes and typing B cell malignancies by flow cytometry and immunofluorescence.


      Flow cytometry and Indirect Immunofluorescence 1:25

      Dilute with isotonic buffer. Use 50 μl of diluted antibody per 1 x 10E6 peripheral blood mononuclear cells (PBMC) in 100 μl buffer.

      ConcentrationPlease refer to the Certificate of Analysis for the lot-specific concentration.
      SpecificityThis specificity of this antibody is equivalent to that of CD19 monoclonal antibodies (Zola et al., 1988, 1989), based on comparative studies, antigen recognition and positive reaction with a CD19 transfected cell line. It detects a 96 kD single chain glycoprotein on the surface of human B lineage cells, including pre-B cells. B cells can be detected in peripheral blood and tissues. The antibody reacts with most B cell malignancies including chronic lymphocytic leukemia and most lymphomas, but not multiple myeloma.

      Cell reactivity:

      Normal:Stains all B lymphocytes in peripheral blood and spleen. Negative on granulocytes, monocytes, platelets, erythrocytes and T lymphocytes.

      Antibody TypeMonoclonal Antibody
      Entrez Gene Number
      Entrez Gene SummaryLymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. This gene encodes a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P15391 # Assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.
      SIZE: 556 amino acids; 61128 Da
      SUBUNIT: Forms a complex with CD21, CD81 and CD225 in the membrane of mature B cells. Interacts with VAV. Interacts with GRB2 and SOS when phosphorylated on Tyr-348 and/or Tyr-378. Interacts with PLCG2 when phosphorylated on Tyr-409.
      SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
      PTM: Phosphorylated upon DNA damage, probably by ATM or ATR.
      DISEASE:SwissProt: P15391 # Defects in CD19 are a cause of hypogammaglobulinemia [MIM:107265].
      SIMILARITY: SwissProt: P15391 ## Contains 2 Ig-like C2-type (immunoglobulin-like) domains.
