PictArrays™ consist of a panel of tiny dots, each comprising reagents required for an individual test printed in the sixteen wells of a specially designed slide with eight detachable 2-well modules. Every test is duplicated in the standard layout of the panel (colored dots in the inset). Control spots are embedded in each panel to ensure proper test performance. This feature cannot be incorporated in traditional ELISA tests. Only 50 microlitres (a drop of blood is 200 microliters) of a highly diluted patient sample is required for testing. The image of the colored end points is captured using the PictImager™, followed by image analysis with Pictorial© which provides an easy to read printout of the results within two minutes of test completion.
PictArrays provide a complete immunodiagnostic solution to test for either a chosen panel of diseases or for multiple markers of a single disease, while enabling easy customization of the panel depending on the specific needs of the user. The technology is unique compared with currently marketed miniaturized, multiplex technology in terms of:
