Anti-N-Cadherin Antibody, clone 13A9

Cadherin-2 (UniProt P19022; also known as CD325, CDw325, N-cadherin, Neural cadherin) is encoded by the CDH2 (also known as CDHN, NCAD) gene (Gene ID 1000) in human. Cadherins constitute a family of calcium-dependent cell-cell adhesion proteins that play important roles in the embryonic development and maintenance of normal tissue architecture. Cadherins are composed of an extracellular domain (a.a. 160-724 of human N-cadherin) with five homologous repeats that mediates adhesion, a single pass transmembrane domain (a.a. 725-745 of human N-cadherin), and a conserved cytoplasmic domain (a.a. 746-906 of human N-cadherin) that interacts with catenins to link cadherins to the actin cytoskeleton. In addition, a known Src substrate p120ctn also modulate the strength of cadherin-dependent adhesion by interacting with cadherins at their intracellular juxtamembrane domain. Cadherins are synthesized as precursor proteins that must be proteolytically cleaved to generate functional, mature proteins. Newly synthesized proN-cadherin (a.a. 1-906) is phosphorylated and proteolytically processed prior to transport to the plasma membrane. In addition, Plakoglobin (gamma-catenin) and beta-catenin associate only with phosphorylated proN-cadherin, whereas p120ctn can associate with both phosphorylated and non-phosphorylated proN-cadherin. The N-terminal signal and propeptide (a.a. 1-25 and 26-159 of of human N-cadherin) region is proteolytically removed and a core N-cadherin-catenin complex is assembled in the endoplasmic reticulum or Golgi compartment prior to localization at the plasma membrane where linkage to the actin cytoskeleton can be established.

Clone 13A9 recognizes N-cadherin, but not P-, E-, or M-cadherin (Knudsen, K.A., et al. (1995). J. Cell Biol. 130(1):67-77).

Bacterially expressed human N-cadherin cytoplasmic domain MBP fusion protein (Knudsen, K.A., et al. (1995). J. Cell Biol. 130(1):67-77).

Epitope: Cytoplasmic domain.

Detect N-cadherin using this Anti-N-Cadherin Antibody, clone 13A9 validated for use in Immunocytochemistry, Immunohistochemistry, Immunoprecipitation, and Western Blotting.

Immunohistochemistry Analysis: A representative lot immunostained the extracellular matrix of the stable plaques and in the fibrous cap region rich in vascular smooth muscle cells (VSMCs) using patients-derived paraffin-embedded internal carotid artery tissue sections (Musumeci, G., et al. (2014). Histol. Histopathol. 29(6):707-719).
Immunohistochemistry Analysis: A representative lot detected strong N-cadherin immunoreactivity in paraffin-embedded rectal cancer (RC) tissues with positive regional lymph node metastasis (RLNM) status, while only weak N-cadherin immunoreactivity was detected in RC with negative RLNM, and no N-cadherin staining was seen in normal colorectal epithelium (Fan, X.J., et al. (2012). Br. J. Cancer. 106(11):1735-1741).
Immunohistochemistry Analysis: A representative lot detected N-cadherin immunoreactivity in formalin-fixed, paraffin-embedded hepatocellular carcinoma (HCC) tissue sections. A significant inverse correlation was found between RUNX3 and N-cadherin expression levels (Tanaka, S., et al. (2012). Int. J. Cancer. 131(11):2537-2546).
Western Blotting Analysis: A representative lot detected an upregulated N-cadherin expression in CCL185 carcinoma cells following transient Epstein-Barr virus (EBV) infection. The EMT-like phenotype remained even after viral loss by culture selection pressure withdrawal (Queen, K.J., et al. (2013). Int. J. Cancer. 132(9):2076-2086).
Western Blotting Analysis: A representative lot detected N-cadherin in Hep3B, Huh7, HLF and SK-Hep1 human hepatocellular carcinoma (HCC) cell lysates (Tanaka, S., et al. (2012). Int. J. Cancer. 131(11):2537-2546).
Western Blotting Analysis: A representative lot detected both the unprocessed (pro-) and processed (mature) forms of N-cadherin in HeLa cell lysate (Wahl, J.K. 3rd., et al. (2003). J. Biol. Chem. 278(19):17269-17276).
Western Blotting Analysis: A representative lot detected N-cadherin in WI-38 human fibroblast lysate, but not in JAr human placental choriocarcinoma cell lysate (Knudsen, K.A., et al. (1995). J. Cell Biol. 130(1):67-77).
Immunocytochemistry Analysis: A representative lot detected N-cadherin immunoreactivity localized primarily at the cell-cell borders by fluorescent immunocytochemistry staining of 1% paraformaldehyde-fixed, methanol-permeabilized HeLa cells (Wahl, J.K. 3rd., et al. (2003). J. Biol. Chem. 278(19):17269-17276).
Immunocytochemistry Analysis: A representative lot detected N-cadherin immunoreactivity colocalized with those of alpha- and beta-catenin by dual fluorescent immunocytochemistry staining of fixed WI-38 human fibroblasts (Knudsen, K.A., et al. (1995). J. Cell Biol. 130(1):67-77).
Immunoprecipitation Analysis: Representative lots co-immunoprecipitated alpha-catenin, beta-catenin, and plakoglobin with N-cadherin from WI-38 human fibroblast and HeLa cell lysates (Wahl, J.K. 3rd., et al. (2003). J. Biol. Chem. 278(19):17269-17276; Knudsen, K.A., et al. (1995). J. Cell Biol. 130(1):67-77).

Western Blotting Analysis: A 1:1000-5000 dilution of this hybridoma culture supernatant detected N-cadherin in HeLa cell lysate.

~140 kDa observed. Target band size appears larger than the calculated molecular weights of 82.03 kDa (mature) and 99.81/97.04 kDa (isoform 1/2 pro-form) due to posttranslational glycosylation and phosphorylation.
