  • General notes

    ab209892 is a carrier-free antibody designed for use in antibody labeling, including fluorochromes, metal isotopes, oligonucleotides, enzymes.

    Our Low endotoxin, azide-free formats have low endotoxin level (≤ 1 EU/ml, determined by the LAL assay) and are free from azide, to achieve consistent experimental results in functional assays.

    This product is a recombinant monoclonal antibody, which offers several advantages including:

    • - High batch-to-batch consistency and reproducibility
    • - Improved sensitivity and specificity
    • - Long-term security of supply
    • - Animal-free production

    Lane 1 : Wild-type HAP1 whole cell lysate

    Predicted band size: 55 kDa
    Observed band size: 55 kDa



    Lanes 1 - 4: Merged signal (red and green). Green - ab191419 observed at 55 kDa. Red - loading control, ab9484, observed at 37 kDa.

    ab191419 was shown to recognize SIRP alpha in wild-type HAP1 cells as signal was lost at the expected MW in SIRPA knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and SIRPA knockout samples were subjected to SDS-PAGE. Ab191419 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab191419).
