Abstract
A device and system for detecting an antigen present in a sample is provided. The system includes a cartridge and a reader device. The cartridge includes a solid support having an addressable array of at least one type of antibody that is specific for a target antigen and forms a complex in the presence of the target antigen, a substrate having a mounting surface for the solid support, Protein M for competitively displacing the target antigen from the complex, and a housing for protecting the substrate. The reader device is configured to detect the antigen in a liquid sample via interaction with the cartridge.
