PGI2 (Prostacyclin) ELISA Kit

Description

Synonym: prostaglandin I2, PGI2. This PGI2 (Prostacyclin) ELISA Kit applies to the in vitro quantitative determination of Universal PGI2 concentrations in serum, plasma and other biological fluids. Type:Competitive, Assay time:1.5h, Detection type:Colormetric, Precision:CV<10%, Assay Range:31.25-2000pg/mL, Sensitivity:18.75pg/mL, Recovery:80%-120%, Cross reactivity:The kit detected PGI2 in the samples and no significant cross-species reactions were found. Detection Principle:This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with PGI2. During the reaction, PGI2 in the sample or standard competes with a fixed amount of PGI2 on the solid phase supporter for sites on the Biotinylated Detection Ab specific to PGI2. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of PGI2 in tested samples can be calculated by comparing the OD of the samples to the standard curve.
