A1-AT (Alpha 1-Antitrypsin) BioAssay(TM) ELISA Kit (Rat)

Sample Type:, Serum, Plasma, Biological Fluids, Intended Use: This BioAssay(TM) kit is a sandwich ELISA for in vitro quantitative measurement of alpha1-AT in rat serum, plasma and other biological fluids, Sensitivity: 3.75ng/mL, Range: 6.25-400ng/mL, Specificity: Rat, Test Principle: This BioAssay(TM) 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 rat alpha1-AT (Alpha 1-Antitrypsin). Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for rat alpha1-AT (Alpha 1-Antitrypsin) and Avidin-Horseradish Peroxidase (HRP) conjugate are 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 rat alpha1-AT (Alpha 1-Antitrypsin), biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding 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 rat alpha1-AT (Alpha 1-Antitrypsin). The concentration of rat alpha1-AT (Alpha 1-Antitrypsin) in samples can be calculated by comparing the OD of the samples to the standard curve.
