  • WB - CD19 Antibody (N-term) AP1494a
    Western blot analysis of lysate from Ramos cell line, using CD19Antibody (N-term)(Cat. #AP1494a). AP1494a was diluted at 1:500. A goat anti-rabbit IgG H&L(HRP) at 1:5000 dilution was used as the secondary antibody. Lysate at 35ug.
  • WB - CD19 Antibody (N-term) AP1494a
    CD19 Antibody (N-term) (Cat.# AP1494a) western blot analysis in Raji cell line lysates (35ug/lane).This demonstrates the CD19 antibody detected the CD19 protein (arrow).
  • WB - CD19 Antibody (N-term) AP1494a
    Western blot analysis of CD19 (arrow) using rabbit polyclonal CD19 Antibody (N-term) (Cat.#AP1494a). 293 cell lysates (2 ug/lane) either nontransfected (Lane 1) or transiently transfected with the CD19 gene (Lane 2) (Origene Technologies).
  • IF - CD19 Antibody (N-term) AP1494a
    Immunofluorescence analysis of CD19 Antibody (N-term) with paraffin-embedded human lymph tissue . 0.05 mg/ml primary antibody was followed by FITC-conjugated goat anti-rabbit lgG (whole molecule). FITC emits green fluorescence.Red counterstaining is PI.
  • FC - CD19 Antibody (N-term) AP1494a
    Flow cytometric analysis of CEM cells using CD19 Antibody (N-term)(bottom histogram) compared to a negative control cell (top histogram). FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.
  • IHC-P - CD19 Antibody (N-term) AP1494a
    Formalin-fixed and paraffin-embedded human lymph reacted with CD19 Antibody (N-term), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.

Lymphocytes 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. CD19 is a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.
