Recombinant Human EpCAM/TROP1 (hFc Tag)

Description :
FAQ COA 已发表文献 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. During embryonic development, EpCAM is detected in fetal lung, kidney, liver, pancreas, skin, and germ cells. In adults, human EpCAM is expressed on basolateral cell membranes of all simple, pseudo-stratified, and transitional epithelia but not on normal squamous stratified epithelia, mesenchymal tissue, muscular tissue, neuro-endocrine tissue, or lymphoid tissue. It is additionally expressed on undifferentiated embryonic stem cells, thymocytes, and dendritic cells. 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. Proteolytic cleavage of EpCAM releases multiple fragments from the ECD as well as a cytoplasmic fragment that can regulate gene transcription. 产品性质 别名 CD326; EGP; EGP-2; EGP314; EGP40; EpCAM; ACSTD1; DIAR5; gp40; HNPCC8; MOC31; TACST-1; TACSTD1; TROP1; ESA; KSA; MIC18; MK1 Uniprot No. P16422 Recombinant Human EpCAM/TROP1Protein is expressed from HEK293Cells with hFc tag at the C-terminal. It contains Gln24-Lys245. 分子量 Approximately 54.2 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Tris-Bis PAGE result. > 95% as determined by SDS-PAGEand HPLC. ELISA DataImmobilized Human EpCAM, hFc Tag at 1g/ml (100l/well) on the plate. Dose response curve for Biotinylated Anti-EpCAM Antibody, hFc Tag with the EC50 of 18.9ng/ml determined by ELISA. 内毒素 1.0EU per 1g of the protein by the LAL method. Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. 复溶 Centrifuge tubes before opening. Reconstituting to a concentration more than 100 g/mL is recommended (usually we use 1mg/mLsolution for lyophilization). Dissolve the lyophilized protein in distilled water.
