Human Factor IX/PTC SimpleStep ELISA® kit is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Factor IX/PTC protein in human serum and plasma. Quantitate Human Factor IX/PTC with 15.884 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
-Single-wash protocol reduces assay time to 90 minutes or less
-High sensitivity, specificity and reproducibility from superior antibodies
-Fully validated in biological samples
-96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (Pre-coated 384 well Microplate SimpleStep ELISA® ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Factor IX also known as Christmas factor or PTC is an important clotting protein in the coagulation cascade. It is a 415 amino acid protein with a mass of approximately 55 kDa. Factor IX is mainly expressed in the liver and then released into the bloodstream where it plays a significant role in blood clotting processes. The recombinant version of this protein referred to as factor IX recombinant is used therapeutically especially in patients who require coagulation support due to factor deficiencies.
The function of factor IX involves its role in the amplification phase of the coagulation cascade. It participates as part of the intrinsic tenase complex which forms on negatively charged phospholipids in the presence of calcium ions. This complex significantly enhances the conversion of factor X to its active form factor Xa an important step in the clotting process. The activity of factor IX can be assessed using assays such as the factor IX activity assay and ELISA allowing for precise measurement of its function and quantity.
Factor IX is integral within the intrinsic pathway of blood coagulation. It interacts with proteins such as factor VIII and factor X. When activated factor IXa forms a complex with the cofactor factor VIIIa on membrane surfaces intensifying the transformation of factor X to factor Xa which then catalyzes the conversion of prothrombin to thrombin. This series of reactions leads to fibrin formation important for stable clot production. Factor IXa also relates to the pathways influencing cellular signaling and hemostasis.
Factor IX deficiencies cause hemophilia B a genetic disorder that leads to improper blood clotting. This disorder is mainly characterized by spontaneous bleeding or severe bleeding after injury. Patients with hemophilia B usually have mutations in the factor IX gene on the X chromosome affecting the protein's function. Successful treatment often involves replacement therapy using factor IX concentrates or the recombinant form. The interaction with proteases such as factor VIIa highlights its importance in therapeutic strategies for bleeding disorders.

Serum of ten individual healthy human female donors was measured in duplicate. Interpolated dilution factor corrected values are plotted (mean +- SD, n=2). The mean Factor IX/PTC concentration was determined to be 4,867.18 ng/mL with a range of 1,062.16 – 8,981.25 ng/mL.
Interpolated concentration of native Factor IX/PTC was measured in duplicate at different sample concentrations. Undiluted samples are as follows: serum 0.15%, plasma (citrate) 0.075%, plasma (EDTA) 0.075%, and plasma (heparin) 0.15%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). Sample dilutions are made in Sample Diluent NS.
SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.
