  • Product overview

    Factor IX Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Factor IX concentrations in cell culture supernatants, serum and plasma.


    A Factor IX specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a Factor IX specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate 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 IX captured in plate.


    Get higher sensitivity in only 90 minutes with Human Factor IX ELISA Kit (ab188393) from our SimpleStep ELISA® range.


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

  • Function

    Factor IX is a vitamin K-dependent plasma protein that participates in the intrinsic pathway of blood coagulation by converting factor X to its active form in the presence of Ca(2+) ions, phospholipids, and factor VIIIa.
  • Tissue specificity

    Synthesized primarily in the liver and secreted in plasma.
  • Involvement in disease

    Defects in F9 are the cause of recessive X-linked hemophilia B (HEMB) [MIM:306900]; also known as Christmas disease.
    Note=Mutations in position 43 (Oxford-3, San Dimas) and 46 (Cambridge) prevents cleavage of the propeptide, mutation in position 93 (Alabama) probably fails to bind to cell membranes, mutation in position 191 (Chapel-Hill) or in position 226 (Nagoya OR Hilo) prevent cleavage of the activation peptide.
    Defects in F9 are the cause of thrombophilia due to factor IX defect (THR-FIX) [MIM:300807]. A hemostatic disorder characterized by a tendency to thrombosis.
  • 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.
  • Domain

    Calcium binds to the gamma-carboxyglutamic acid (Gla) residues and, with stronger affinity, to another site, beyond the Gla domain.
  • Post-translational
    modifications

    Activated by factor XIa, which excises the activation peptide.
    The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains.
  • Cellular localization

    Secreted.

    Answer

    Thank you for your call yesterday, and I apologize again for the delay in gettingthis information to you.

    I have contacted the production lab again, and they haverecentlydone further testing to determine that the 400 ng standard isequal to 80 mU. So, the 100 ng/mL standard solution is 20 mU/mL, etc. This information wasgleaned bycomparing ultra pure protein and WHO reference standard, and the assay has been calibrated against many parameters.

    I hope this information will be useful, but if there is anything else that we can do for you please let me know and I'll be happy to help.

    Question

    I want to use this kit for xenograft studies.  Does this kit cross-react with mouse Factor IX?

    Asked on Feb 03 2012

    Answer

    Thank you for contacting us.  Based on the lab's data, this kit does not react with mouse Factor IX.  I would still recommend doing a negative control with a WT mouse sample to ensure that your data is accurate and that you are only measuring human Factor IX.  I hope this helps, please let me know if you need any additional information.
