Epithelial Cellular Adhesion Molecule (EpCAM), also known as KS1/4, gp40, GA733-2, 17-1A, and TROP1, is a 40 kDa transmembrane glycoprotein that consists of a 242 amino acid (aa) extracellular domain with two EGFlike repeats, a 23 aa transmembrane segment, and a 26 aa cytoplasmic domain. It is up-regulated on actively proliferating epithelial tissues, during adult liver regeneration, and on many epithelial cell-derived carcinomas. EpCAM functions as a homophilic cell adhesion molecule. It associates into tetramers and forms complexes in cis with Claudin-7, CD44v6, TSPAN8, CD9, Integrin alpha 3, and Annexin A1 that can interfere with cell adhesion. Specifications Synonyms CD326; EGP; EGP-2; EGP314; EGP40; EpCAM; ACSTD1; DIAR5; gp40; HNPCC8; MOC31; TACST-1; TACSTD1; TROP1; ESA; KSA; MIC18; MK1 Uniprot No. P16422 Source Recombinant Biotinylated Human EpCAM/TROP1 Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Gln24-Lys245. Source The protein has a predicted MW of 30.1 kDa. Due to glycosylation, the protein migrates to 30-45 kDa based on Tris-Bis PAGE result. Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Purity > 95% as determined by SDS-PAGE and HPLC Endotoxin < 1.0 EU per 1μg of the protein by the LAL method. Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100μg/mL is recommended. Dissolve the lyophilized protein in distilled water. Storage The products are shipped with ice pack and can be stored at -20℃ for 1 year. 2-7 days, 2 to 8 °C under sterile conditions after reconstitution.3 -6 months, -20 to -80°C under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.
