Overview

  • Product name

    Anti-Islet 1 antibody [EPR10362] - BSA and Azide free
    See all Islet 1 primary antibodies

  • Description

    Rabbit monoclonal [EPR10362] to Islet 1 - BSA and Azide free

  • Host species

    Rabbit

  • Specificity

    In western blot, we observe a specific band at ~40kDa which is not seen in KO cell lines. A cross-reactive band was observed in the wild-type and knockout cells. The additional band below this band of interest is seen at ~38kDa in both the WT and KO cells. We are unsure as to the identity of these extra bands.

  • Tested applications

    Suitable for: WB, IHC-P, IPmore details
    Unsuitable for: Flow Cyt or ICC/IF

  • Species reactivity

    Reacts with: Human
    Does not react with: Mouse, Rat

  • Immunogen

    Recombinant fragment within Human Islet 1 aa 1 to the C-terminus. The exact sequence is proprietary.

    Lanes 1 - 4: Merged signal (red and green). Green - ab178400 observed at 40 kDa. Red - loading control, ab18058, observed at 130 kDa.

    ab178400 was shown to recognize Islet 1 in wild-type HAP1 cells as signal was lost at the expected MW in Islet 1 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and Islet 1 knockout samples were subjected to SDS-PAGE. Ab178400 and ab18058 (Mouse anti-Vinculin 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 (ab178400).
