    Predicted band size: 36 kDa
    Observed band size: 37,45 kDa
    why is the actual band size different from the predicted?



    The bands detected by ab92495 are consistent with what have been described in PMID: 20876574 and PMID: 17389606.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human tonsil tissue sections labeling CD23 with Purified ab92495 at 1/400 dilution (0.5 µg/ml). Heat mediated antigen retrieval was performed using ab93684 (Tris/EDTA buffer, pH 9.0). ImmunoHistoProbe one step HRP Polymer (ready to use) was used as the secondary antibody. Negative control: PBS instead of the primary antibody. Hematoxylin was used as a counterstain.

  • Flow Cytometry analysis of Human peripheral blood mononuclear (PBMC) cells labeling CD23 with purified ab92495 at 1:20 dilution (10 µg/ml) (Red). A Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) secondary antibody was used at 1:2000. Isotype control - Rabbit monoclonal IgG (Left).

    Cells were stained with rabbit IgG (Left) or ab92495 (Right). Then stained with anti-CD19 conjugated to Alexa Fluor® 647. Gated on viable cells.
