  • 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.

  • Research areas
  • Relevance
    Factor IX is a vitamin K-dependent coagulation factor IX that circulates in the blood as an inactive zymogen. This factor is converted to an active form by factor XIa, which excises the activation peptide and thus generates a heavy chain and a light chain held together by one or more disulfide bonds. The role of this activated factor IX in the blood coagulation cascade is to activate factor X to its active form through interactions with Ca+2 ions, membrane phospholipids, and factor VIII. Alterations of this gene, including point mutations, insertions and deletions, cause factor IX deficiency, which is a recessive X-linked disorder, also called hemophilia B or Christmas disease.

    What is the activity of the provided standards?

    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...

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

    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 Fac...
