array technology surface plasmon resonance surface plasmon resonance array SPRImager This array technology allows the screening of binding abilities of hundreds or thousands of biomolecules (small molecule, peptide, protein, sugar, lipid, nucleic acid, and their fragments) printed onto the gold-coated chip by using an instrument (micro-arrayer) that is capable of spotting liquid samples in a reproducible manner onto a planar support. The ordered protein array can then be probed with a non-labelled sample (small molecule, peptide, protein, sugar, lipid, nucleic acid, and their fragments) to identify the baits that can bind to it. This is done in real time, allowing direct measurement of both the on-rate and the off-rate and of the affinity constant of complex formation on each spot.
