  • Synonym
    FAP,FAPalpha,SIMP,Seprase,APCE
  • Source
    Human FAP, His Tag(FAP-H5244) is expressed from human 293 cells (HEK293). It contains AA Leu 26 - Asp 760 (Accession # Q12884-1).
    Predicted N-terminus: His
  • Molecular Characterization
    FAP Structure

    This protein carries a polyhistidine tag at the N-terminus.

    The protein has a calculated MW of 86.9 kDa. The protein migrates as 95 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 0.1 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

    >95% as determined by SEC-MALS.

  • Formulation

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

Bioactivity-ELISA
 FAP ELISA

Immobilized Human FAP, His Tag (Cat. No. FAP-H5244) at 1 μg/mL (100 μL/well) can bind Monoclonal Anti-FAP (FAP5) Antibody, Mouse IgG2a with a linear range of 0.1-2 ng/mL (QC tested).

 FAP ELISA

Immobilized Human FAP, His Tag (Cat. No. FAP-H5244) at 1 μg/mL (100 μL/well) can bind Anti-FAP (Sibrotuzumab) Antibody,Human IgG1 with a linear range of 0.1-2 ng/mL (Routinely tested).

Bioactivity-SPR
 FAP SPR

Anti-FAP Antibody, Mouse IgG2a (FAP5) captured on CM5 chip via anti-mouse antibodies surface can bind Human FAP, His Tag (Cat. No. FAP-H5244) withan affinity constant of 9.47 nM asdetermined in a SPR assay (Biacore 8K) (Routinely tested).

Bioactivity

Measured by its ability to convert the substrate benzyloxycarbonyl-Gly-Pro-7-amido-4-methylcoumarin (Z-GP-AMC) to Z-Gly-Pro and 7-amino-4-methylcoumarin (AMC). The specific activity is >8000 pmol/min/µg (QC tested).

  • Background
    FAP (also known as seprase) is a Type II transmembrane serine protease. Both plasma membrane and soluble forms exhibit post-proline cleaving endopeptidase activity, with a marked preference for Ala/Ser-Gly-Pro-Ser/Asn/Ala consensus sequences. Degrade also gelatin, heat-denatured type I collagen. Also has dipeptidyl peptidase activity, with a preference for Ala-Pro, Ile-Pro, Gly-Pro, Arg-Pro and Pro-Pro. The plasma membrane form, in association with either DPP4, PLAUR or integrins, is involved in the pericellular proteolysis of the extracellular matrix (ECM), and hence promotes cell adhesion, migration and invasion through the ECM. Promotes glioma cell invasion through the brain parenchyma by degrading the proteoglycan brevican. Acts as a tumor suppressor in melanocytic cells through regulation of cell proliferation and survival in a serine protease activity-independent manner.
