Product Datasheets
Carrier Free
CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.
In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Scientific Data
Immobilized Recombinant Cynomolgus Monkey EpCAM/TROP-1 His-tag protein (Catalog # 10406-EP) supports the adhesion of L Cells mouse fibroblast cells. The ED50 for this effect is 0.3-1.8 μg/mL.
2 μg/lane of Recombinant Cynomolgus Monkey EpCAM/TROP-1 His-tag (Catalog # 10406-EP) was resolved with SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized by Coomassie® Blue staining, showing bands at 60-66 kDa and 120-150 kDa, respectively.
Reconstitution Calculator
Background: EpCAM/TROP1
Epithelial Cellular Adhesion Molecule (EpCAM), also known as KS1/4, gp40, GA733-2, 17-1A, and TROP-1, is a 40 kDa transmembrane glycoprotein. Based on its similarity with human EpCAM, Cynomolgus EpCAM is predicted to consist of a 242 amino acid (aa) extracellular domain with two epidermal growth factor like (EGF like) repeats within the cysteine rich N-terminal region, a 23 aa transmembrane domain, and a 26 aa cytoplasmic domain. Cynomolgus and human EpCAM share 93% aa sequence identity (1). 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 (2). It is additionally expressed on undifferentiated embryonic stem cells, thymocytes, and dendritic cells (3-5). It is up-regulated on actively proliferating epithelial tissues, during adult liver regeneration, and on many epithelial cell-derived carcinomas (2, 6). EpCAM functions as a homophilic cell adhesion molecule (7). It associates into tetramers and forms complexes in cis with Claudin-7, CD44v6, TSPAN8, CD9, Integrin alpha 3, and Annexin A1 (8-11) that can interfere with cell adhesion (12, 13). Proteolytic cleavage of EpCAM releases multiple fragments from the ECD as well as a cytoplasmic fragment that can regulate gene transcription (14-16).
