Human CEACAM-5 Protein, Llama IgG2b Fc Tag, low endotoxin (MALS verified)

  • Synonym
    CEACAM-5,CD66e,CEA,Meconium antigen 100
  • Source
    Human CEACAM-5, Llama IgG2b Fc Tag (CE5-H5259) is expressed from human 293 cells (HEK293). It contains AA Pro 593 - Ser 675 (Accession # P06731-1).
    Predicted N-terminus: Pro 593
  • Molecular Characterization
    Online(Pro 593 - Ser 675) P06731-1

    This protein carries a llama IgG2b Fc tag at the C-terminus.

    The protein has a calculated MW of 36.7 kDa. The protein migrates as 50-60 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 0.01 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

Immobilized Human CEACAM-5, Llama IgG2b Fc Tag (Cat. No. CE5-H5259) at 1 μg/mL (100 μL/well) can bind Anti-CEACAM-5 (labetuzumab) Antibody, Human IgG1 with a linear range of 0.01-0.313 μg/mL (QC tested).

Please note that there may be a cross-reaction between anti-human IgG Fc antibodies and llama IgG Fc tag, also between anti-llama IgG Fc antibodies and human IgG Fc tag.
  • 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.
