CDCP1 is a novel, 135kD cell surface glycoprotein that is found on tumor, stem cells, keratinocytes and colonic epithelial cells. It is reported that this protein is overexpressed in colon and lung cancers. It is a type I transmembrane (TM) protein that is involved with cell adhesion. Mouse CDCP1 is synthesized as an 833 amino acid (aa) precursor. It contains an extracellular region with three CUB domains (aa30-667) and a phosphotyrosine site at Tyr731. When unligated, CDCP1 can be proteolytically cleaved between aas 270-300. This generates an 80kD TM protein that may be missing the N-terminal CUB domain (aa221-350). Over aas 25-667, mouse CDCP1 is 83% and 92% aa identical to human and rat CDCP1, respectively.
Catalog #C2566-01
ApplicationsSuitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.
Recommended DilutionsDirect ELISA: 0.5-1.0ug/ml. The detection limit of recombinant mouse CDCP1 is ~1ng/well.
Western Blot: 0.1-0.2ug/ml. The detection limit of recombinant mouse CDCP1 is ~25ng/lane under non-reducing and reducing conditions.
Immunohistochemistry: 5-15ug/ml detects CDCP1 in cells and tissues.
Optimal dilutions to be determined by the researcher.
