Quantibody® is an array-based multiplex ELISA system for simultaneous quantitative measurement of multiple cytokines, growth factors, proteases, soluble receptors, and other proteins in a wide variety of sample types. Quantibody combines the high specificity and sensitivity of ELISA with the high throughput of the glass chip-based array. With this platform, only 50 µL of sample is needed for quantification of up to 40 proteins in quadruplicate. Each 75 mm x 25mm glass slide is spotted with 16 identical antibody arrays. The slide comes with a 16-well removable gasket and chamber assembly that allows for simultaneous processing.
