Human PAPPA (Pregnancy Associated Plasma Protein A) ELISA Kit
The Human PAPPA (Pregnancy-Associated Plasma Protein A) ELISA Kit is specifically designed for the precise measurement of PAPPA levels in human samples such as serum, plasma, and cell culture supernatants. With its high sensitivity and specificity, this kit ensures accurate and reproducible results, making it an excellent tool for various research applications.PAPPA is a vital protein involved in pregnancy-related processes, including fetal development and maternal health.
Abnormal levels of PAPPA have been linked to complications during pregnancy, such as preeclampsia and fetal growth restriction. Studying PAPPA levels can provide valuable insights into these conditions and aid in the development of effective diagnostic and therapeutic strategies.Get your Human PAPPA ELISA Kit today and unlock the potential to advance your research in the fields of obstetrics, gynecology, and reproductive biology.

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 PAPPA. 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 PAPPA 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 PAPPA, 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 PAPPA. You can calculate the concentration of Human PAPPA in the samples by comparing the OD of the samples to the standard curve.
