Bio-Plex Suspension Array System is based on the Luminex’s xMAP technology. It permits the simultaneous analysis of up to 100 different biomolecules (proteins, peptides or nucleic acids) in a single well.
Currently, the CGS uses the Bio-Plex 200 system with Bio-Plex Manager 5.0 Software to provide core services.
The technology can be applied to protein expression profiling such as quantitative measurement of cytokines.
