The list of scientific publications below includes direct references to Label-Enhanced SPR work, but also some SPR papers of general background interest to help understand and practice the art of LE-SPR.
- J.G. Quinn, K.E. Pitts, M. Steffek, M.M. Mulvihill “Determination of affinity and residence time of potent drug-target complexes by label-free biosensing”, J. Med. Chem. 61 (2018) 5154-5161.
- While this work is not strictly LE-SPR, it’s a very interesting paper about stretching the limits of determining extremely slow dissociation constants of drug-target complexes. Scientists at Genentech used dye-labelled ‘chaser’ probes to get an enhanced SPR signal. Unfortunately, for reasons of throughput, the work was done on the Biacore™ 8K which does not fully support LE-SPR. Potentially even longer residence times could be studied by running a similar method on e.g. Biacore™ T200 utilizing its full LE-SPR capabilities.
