  • Product overview

    Abcam’s Factor X Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Factor X concentrations in plasma, serum, milk, urine, saliva and cell culture supernatants.

    A Factor X specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a Factor X specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Complex is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of Factor X captured in plate.

    The entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.

  • Research areas

  • Function

    Factor Xa is a vitamin K-dependent glycoprotein that converts prothrombin to thrombin in the presence of factor Va, calcium and phospholipid during blood clotting.
  • Tissue specificity

    Plasma; synthesized in the liver.
  • Involvement in disease

    Factor X deficiency
  • Sequence similarities

    Belongs to the peptidase S1 family.
    Contains 2 EGF-like domains.
    Contains 1 Gla (gamma-carboxy-glutamate) domain.
    Contains 1 peptidase S1 domain.
  • Post-translational

    The vitamin K-dependent, enzymatic carboxylation of some glutamate residues allows the modified protein to bind calcium.
    N- and O-glycosylated. O-glycosylated with core 1 or possibly core 8 glycans.
    The activation peptide is cleaved by factor IXa (in the intrinsic pathway), or by factor VIIa (in the extrinsic pathway).
    The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains.

Our Abpromise guarantee covers the use of ab108832 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Sandwich ELISA Use at an assay dependent dilution.


  • Standard curve with background signal subtracted (duplicates; +/- SD).

  • Factor X measured in undiluted culture supernatants with MCF7 levels below level of detection (duplicates +/- SD).

  • Factor X measured in biological fluids (duplicates +/- SD). Serum and plasma were tested at 1/300-1/3000; other samples at 1/1-1/30.

Thank you for alerting us to this mistake in the protocol.

I can confirm that the biotinylated antibody (page 10, step 5) should be incubated for 1 hour.

The protocol will be up-dated as soon as possible.

We wish you good luck with your experiments and a good day.
