  • 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
    modifications

    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.

Answer

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.

Answer

Thank you for your inquiry.

ab108832 may be storedfor up tosix monthat 2 to 8°C or -20°C from the date of shipment.

Thiskits as all our products is covered by our Abpromiseguarantee for six month afterdate of purchase:

https://www.abcam.com/abpromise

Opened diluents may be stored for up to 1 month at 2 to 8°C.

Please store reconstituted reagents at -20°C or below. Opened unused strip wells may bereturned to the foil pouch with the desiccant pack, reseal along zip-seal and may be stored for up to 1 month in a vacuum desiccator.

I can confirm that the lead time is currently 1-2 weeks.

I hope this information is helpful. Please do not hesitate to contact me again with any further questions.
