SpecificityThis assay has high sensitivity and excellent specificity for detection of Human PKR2. No significant cross-reactivity or interference between Human PKR2 and analogues was observed. Note: Limited by current skills and knowledge, it is impossible for us to complete the cross- reactivity detection between Human PKR2 and all the analogues, therefore, cross reaction may still exist.
Intended UseHuman PKR2 ELISA Kit allows for the in vitro quantitative determination of PKR2 , concentrations in serum, Plasma , tissue homogenates and Cell culture supernates and Other biological fluids.
StorageFor 5-7days:Store the whole kit at 4℃
For a Long time :Store the Substrate at 4℃, other reagent should store at -20℃.
Product Description specificalDescription: The kit is a sandwich enzyme immunoassay for in vitro quantitative measurement of PKR2 in human serum, plasma and other biological fluids
Principle of the Assay: This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human PKR2. Standards or samples are added to the appropriate micro ELISA plate wells and bound by the specific antibody. Then a biotinylated detection antibody specific for Human PKR2 and Avidin-Horseradish Peroxidase (HRP) conjugate is added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human PKR2, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid 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 PKR2. You can calculate the concentration of Human PKR2 in the samples by comparing the OD of the samples to the standard curve.
