Four slides can be nested into a tray which matches a standard microplate footprint and allows for automated robotic high throughput process of 64 arrays simultaneously For cytokine quantification the array specific cytokine standards whose concentration has been predetermined are provided to generate a standard curve for each cytokine In a real experiment standard cytokines and samples will be assayed in each array simultaneously through a sandwich ELISA procedure By comparing signals from unknown samples to the standard curve the cytokine concentration in the samples will be determined Quantibody array kits have been confirmed to have similar detection sensitivity as traditional ELISA Our current high density Quantibody kits allow scientists to quantitatively determine the concentration of 660 human 200 mouse and 67 rat cytokines in a single experiment This is not only one of the most efficient products on the market for cytokine quantification but makes it more affordable for quantification of large number of proteins Simultaneous detection of multiple cytokines undoubtedly provides a powerful tool for drug and biomarker discovery III How It Works TTT d 4 Antibody array support n Y Y Y glass slide Incubation of sample amp standard protein cocktail w of 1 2 O Incubation with biotinylated antibody cocktail 7 3 v 1 2 hours siii Incubation with Cy3 equivalent dye labeled streptavidin 12.
