The PIVKA-II ELISA Kit is specifically designed for the precise and reliable detection of PIVKA-II levels in human serum samples. This kit offers high sensitivity and specificity, ensuring accurate and reproducible results for researchers studying conditions such as liver disease, vitamin K deficiency, and hepatocellular carcinoma.PIVKA-II, also known as protein induced by vitamin K absence or antagonist-II, is a protein produced in the liver that is elevated in individuals with impaired vitamin K metabolism.
Monitoring PIVKA-II levels can provide valuable insights into liver function and vitamin K status, making it a valuable biomarker for diagnostic and research purposes.With easy-to-follow instructions and all necessary components included, the PIVKA-II ELISA Kit is a convenient and efficient tool for detecting and quantifying PIVKA-II levels in human samples. Researchers can confidently rely on this kit for accurate and consistent results in their studies.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human PIVKA-Ⅱ. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human PIVKA-Ⅱ and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human PIVKA-Ⅱ, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human PIVKA-Ⅱ. You can calculate the concentration of Human PIVKA-Ⅱ in the samples by comparing the OD of the samples to the standard curve.
