Assay Principle

To detect an antigen using this toolkit a primary antibody is spotted onto the nitrocellulose membrane encapsulated within the specially designed plastic test cartridge. 

When the sample is applied to the cartridge any antigen present will bind to the capture antibody immobilized on the membrane. This binding event is subsequently detected by the formation of a sandwich through the binding of a Gold NanoUrchin conjugated primary antibody to the bound antigen. A positive sample will be indicated by the formation of a blue spot on the membrane, figure 1.
