The Glycogen Synthase 2, Liver (GYS2) BioAssay™ ELISA Kit is a quantitative sandwich assay for the detection of GYS2 in human serum, plasma and other biological fluids.
Specificity:Recognizes human GYS2. No significant crossreactivity or interference between human GYS2 and analogues was observed.
Test Principle:The microtiter plate provided in this kit has been pre-coated with an antibody specific to human GYS2. Standards or samples are then added to the appropriate microtiter plate wells and incubated. Then a biotin-conjugated antibody specific to GYS2 is added. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Free components are washed away. The substrate solution is added, only those wells that contain GYS2, biotin-conjugated antibody and enzyme-conjugated Avidin will apear blue in color. The enzyme-substrate reaction is terminated by the addition of sulfuric acid solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450nm ± 2nm. The OD value is proportional to the concentration of human GYS2. The concentration of GYS2 in the sample is then determined by comparing the O.D. of the sample to the standard curve.
Precaution:The Stop Solution (383198K) included for use with this kit is an acid solution. Wear eye, hand, face, and clothing protection when using this material.
Storage and Stability:Store *383198A, *383198B, *383198D and *383198E at -20°C. Store all the other components at 4°C. Unused kit is stable for 6 months after receipt. Once kit components are opened, it is highly recommended to use remaining reagents within 1 month provided this is within the expiration date of the kit. For maximum recovery of product, centrifuge the original vials after thawing and prior to removing the cap.
