Cayman EpCAM Rabbit Monoclonal Antibody (Clone 28)

Epithelial cell adhesion molecule (EpCAM) is a transmembrane glycoprotein.¹ It is composed of an extracellular domain (EpEX) that contains an N-domain, a thyroglobulin type-IA domain, and a C-domain, a transmembrane domain, and an intracellular domain (EpIC). EpEX undergoes proteolytic cleavage by disintegrin and metalloproteinase domain-containing protein 17 (ADAM17/TACE) to release soluble EpEX, and γ-secretase cleaves EpCAM at two sites to release a soluble extracellular amyloid-β-like fragment and EpIC. EpCAM is ubiquitously expressed in epithelial tissues but is also found in stem and progenitor cells and tight junctions.^2,3 It is involved in cell adhesion, transport, polarity, proliferation, and motility and signals through novel PKC (nPKC), Wnt, and embryonic RAS (ERAS)/Akt pathways.² Knockdown of EPCAM decreases proliferation, migration, and invasion of breast cancer cells in vitro.⁴ Epcam^-/- mice develop congenital tufting enteropathy (CTE), a disease characterized by hemorrhagic diarrhea, colon crypt hyperplasia, intestinal tufts, and villous atrophy.⁵ Increased protein levels of EpCAM are frequently found in tumors from patients with diverse cancer types.⁶ Cayman’s EpCAM Rabbit Monoclonal Antibody (Clone 28) can be used for ELISA, ELISA (detection), flow cytometry (FC), immunocytochemistry (ICC), immunofluorescence (IF), immunohistochemistry paraffin (IHC-P), immunoprecipitation (IP), and Western blot (WB) applications. The antibody recognizes EpCAM at 34 kDa from human samples. However, due to glycosylation the antibody may recognize EpCAM at approximately 38-40 kDa.
