Analysis Note

ControlHuman pancreas tumor tissue lysate

Application

Western Blotting Analysis: 2 µg/mL of this antibody detected CDCP1 in a panel of human tumor tissue lysates.

Immunohistochemistry Analysis: A 1:100 and a 1:500 dilution from a representative lot detected CDCP1 in human breast carcinoma sections.

Anti-CDCP1 Antibody is a highly specific rabbit polyclonal antibody, that targets CUB domain-containing protein 1 & has been tested in western blotting & IHC (Paraffin).

General description

CUB domain-containing protein 1 (CDCP1) is also called Membrane glycoprotein gp140, Subtractive immunization M plus HEp3-associated 135 kDa protein (SIMA135), Transmembrane and associated with src kinases and CD_antigen 318. CDCP1 is part of the tetraspanin web involved in tumor progression and metastasis. CDCP1 may also be involved in cell adhesion, cell matrix association and regulation of anchorage versus migration or proliferation versus differentiation via phosphorylation status. CDCP1 is a possible marker for leukemia diagnosis, and for subsets of immature hematopoietic stem cell. CDCP1 is highly expressed in mitotic cells, skeletal muscle, colon, many human tumor cell lines, colorectal cancer, breast carcinoma and lung cancer. CDCP1 may also be found in cells phenotypically similar to mesenchymal stem cells and neural stem cells.

Immunogen

KLH-conjugated linear peptide corresponding to the cytoplasmic domain of human CDCP1.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.

Quality

Evaluated by Western Blotting in human pancreas tumor tissue lysate.

Western Blotting Analysis: 2 µg/mL of this antibody detected CDCP1 in 10 µg of human pancreas tumor tissue lysate.

Specificity

Other Homologies: Mouse and Rat (77% sequence homology).

This antibody recognizes the cytoplasmic domain of CDCP1.

Target description

~135 kDa and ~70 kDa observed. Uniprot describes 3 isoforms at 92 kDa, 72 kDa, and 38 kDa, due to alternative splicing. The full length and cleaved form of CDCP1 have been observed at ~135 kDa and ~70 kDa (Casar, B., et al. (2012). Oncogene 31(35):3924-3938.). Uncharacterized band(s) may be observed in some cell lysates.
