Biotinylated Human CEACAM-5 / CD66e Protein, His,Avitag™

  • Synonym
    CEACAM-5,CD66e,CEA,Meconium antigen 100
  • Source
    Biotinylated Human CEACAM-5, His,Avitag (CE5-H82E0) is expressed from human 293 cells (HEK293). It contains AA Lys 35 - Ala 685 (Accession # P06731-1).
    Predicted N-terminus: Lys 35
  • Molecular Characterization
    Online(Lys 35 - Ala 685) P06731-1

    This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag.

    The protein has a calculated MW of 75.0 kDa. The protein migrates as 90-120 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Biotinylation
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Biotin:Protein Ratio
    The biotin to protein ratio is 0.5-1 as determined by the HABA assay.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 150 mM Potassium glutamate, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • Background
    Carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5) is also Carcinoembryonic antigen (CEA), Meconium antigen 100, CD antigen CD66e, CEACAM5 belongs to the immunoglobulin superfamily and CEA family. CEACAM5 contains seven Ig-like (immunoglobulin-like) domains. CEACAM5 is homodimer protein which binding of E.coli Dr adhesins leads to dissociation of the homodimer. CEACAM5 is cell surface glycoprotein that plays a role in cell adhesion and in intracellular signaling. CEACAM5 is receptor for E.coli Dr adhesins.
