This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. Human Cripto-1 (CR-1), also known as Teratocarcinoma-derived growth factor 1 (TDGF1), is a member of the epidermal growth factor (EGF)-GFC family and has been implicated in both embryogenesis and carcinogenesis.  During early vertebrate development, CR-1 functions as a co-receptor for Nodal, a transforming growth factor b (TGFb) family member, and is essential for mesoderm and endoderm formation and anterior-posterior and left-right axis establishment.  In adult tissues, CR-1 is expressed at a low level in all stages of mammary gland development, and expression increases during pregnancy and lactation.  Over-expression of CR-1 in mouse mammary epithelial cells leads to their transformation in vitro, and when injected in mammary glands, CR-1 produces ductal hyperplasias.

Application Note

This affinity purified antibody has been tested for use in ELISA and western blotting.  Specific conditions for reactivity should be optimized by the end user.  Expect a band approximately 21 kDa in size corresponding to Cripto-1 by western blotting in the appropriate cell lysate or extract.  Cripto-1 is reported as a 188 amino acid protein with a molecular weight of 21.1 kDa.


This product was affinity purified from monospecific antiserum by immunoaffinity chromatography. This antibody is specific for human Cripto-1 protein.  A BLAST analysis was used to suggest limited cross-reactivity with Cripto-1 from mouse based on a 70% homology with the immunizing sequence.  Expect cross-reactivity with human Cripto-3 (TDGF2) based on very high levels of sequence conservation.  Cross-reactivity with Cripto-1 from other sources has not been determined.
