3. Application of our process to other solid-phase detection formats

3.1 Immunoprinting and its limitations

Immunoassay is one of the most widely used methods for analyzing and detecting proteins present in complex media. First, the various components of a sample are separated by gel electrophoresis and then transferred to a solid phase (nitrocellulose, nylon or polyvinylidene fluoride (PVDF) membrane). Proteins of interest are identified using specific antibodies whose presence is revealed by the production of a signal. The markers used to obtain the signal are either directly coupled to the specific antibody...
