    ab226355 was shown to react with CD133 in wild-type HAP1 cells in western blot. Loss of signal was observed when PROM1 knockout sample was used. Membranes were blocked in 3 % milk in TBS-T (0.1 % Tween®) before incubation with ab226355 overnight at 4°C at a 1 in 1000 dilution. Blots were incubated with HRP conjugated Goat anti-Rabbit (H+L) secondary antibody at 1/5000 for 1 hour at room temperature before development with ECL reagent and imaging.

    Immunohistochemical analysis of paraffin-embedded human pancreatic cancer tissue labeling CD133 with ab226355 at 1/1000 dilution, followed by a Goat Anti-Rabbit IgG H&L (HRP), ready to use. Apical/endoluminal staining on ducts of human pancreatic cancer (PMID: 18261235) is observed. Counter stained with hematoxylin.
    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a Goat Anti-Rabbit IgG H&L (HRP), ready to use.
    Perform heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab226355).
