  • Source
    Biotinylated Rhesus macaque EpCAM / TROP1 Protein, His,Avitag(EPM-R82E3) is expressed from human 293 cells (HEK293). It contains AA Gln 24 - Lys 265 (Accession # Q1WER1).
    Predicted N-terminus: Gln 24
  • Molecular Characterization
    EpCAM Structure

    This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™)

    The protein has a calculated MW of 31 kDa. The protein migrates as 37-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Labeling
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Protein Ratio
    Passed as determined by the HABA assay / binding ELISA.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

The purity of Biotinylated Rhesus macaque EpCAM / TROP1 Protein, His,Avitag (Cat. No. EPM-R82E3) is more than 90% and the molecular weight of this protein is around 28-40 kDa verified by SEC-MALS.

  • Background
    EpCAM is also known as CO171A, EGP, EGP40,GA7332, KSA, M4S, MIC18, MK1, TROP1, hEGP2, and is a pan-epithelial differentiation antigen that is expressed on almost all carcinomas as 17-1A(mAb) antigen. Its constitutional function is being elucidated. It is intricately linked with the Cadherin-Catenin pathway and hence the fundamental WNT pathway responsible for intracellular signaling and polarity. The epithelial cell adhesion molecule (Ep-CAM) is known to express in most epithelial malignancies and was reported as a tumor marker or a candidate of molecular targeting therapy.
    Ep-CAM cross signaling with N-cadherin involves Pi3K, resulting in the abrogation of the cadherin adhesion complexes in epithelial cells was reported. And Epithelial cell adhesion molecule (Ep-CAM) recently received increased attention as a prognostic factor in breast cancer.
