The Mucin 2 (MUC2) BioAssay™ ELISA Kit is a sandwich ELISA for in vitro quantitative measurement of MUC2 in human serum, plasma and other biological fluids.
Specificity:Recognizes human MUC2. No significant crossreactivity or interference between human MUC2. and analogues was observed.
Test Principle:This BioAssay™ 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 MUC2. 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 human MUC2 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 human MUC2, 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 450nm ± 2nm. The OD value is proportional to the concentration of human MUC2. The concentration of human MUC2 in samples can be calculated by comparing the OD of the samples to the standard curve.
Precaution:The Stop Solution (383761K) 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 *383761A, *383761B, *383761D and *383761E 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.
