IHC-P Use at an assay dependent concentration.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 17 kDa (predicted molecular weight: 21 kDa).


  • Function
    Could play a role in the determination of the epiblastic cells that subsequently give rise to the mesoderm.
  • Tissue specificity
    Preferentially expressed in gastric and colorectal carcinomas than in their normal counterparts.

  • ICC/IF image of ab19917 stained mouse embryonic stem cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab19917, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
  • All lanes : Anti-Cripto1 antibody (ab19917) at 1 µg/ml

    Lane 1 : Human Embryonic Stem Cell Lysate at 20 µg
    Lane 2 : Cripto protein at 0.1 µg
    Lane 3 : Human Embryonic Stem Cell Lysate at 20 µg with Human Cripto1 peptide (ab23310) at 1 µg/ml
    Lane 4 : Cripto protein at 0.1 µg with Human Cripto1 peptide (ab23310) at 1 µg/ml

    All lanes : Rabbit IgG secondary antibody (ab28446) at 1/10000 dilution

    Predicted band size: 21 kDa

    The 17 kDa band detected in human embryonic stem cells may correspond with Cripto that has had its signal sequence cleaved. The Cripto bands were blocked with the immunizing peptide, ab23310.

  • Anti-Cripto antibody, ab19917, stained the membrane of human embryonic stem cells at a dilution of 1/100.
  • The image shows staining of human pancreas tissue. Staining was nuclear in some islet cells and cytoplasmic in some cells of the acini. Antigen retrieval was performed using Citrate at pH6. Nuclear localization of Cripto protein has been described in the literature: Gong YP et al. Eur J Surg Oncol, 2006.
