HT Label-Free Screening and Kinetic Analysis of Small Molecules and Biologics

DESCRIPTION provided by applicant Real time label free technologies such as surface plasmon resonance biosensors provide high resolution information about the kinetics affinity stoichiometry activity and specificity of two or more binding partners While the application f biosensors is well established current instrumentation has limited sampling throughput Screens of even a fairly small chemical library e g compounds require days to weeks to complete using traditional label free instruments Because of the quality of the data generated by SPR drug discovery scientists are clamoring to use enhanced biosensors as a screening tool for small molecule applications however lack of throughput hinders their ability to move in this direction We propose to develop a biosensor platform that has increased throughput yet maintains the data quality and ease of use to which researchers are accustomed We will couple our novel Continuous Flow Microspotter CFM with an enhanced sensitivity SPR biosensor from BiOptix to enable label free screening and kinetic analsyis of small molecules and biologics In high throughput screening mode our channel integrated CFM E biosensor platform will be capable of collecting data for andgt samples in less than hours a sampling rate x faster than fastest small molecule capable label free biosensor the Biacore PUBLIC HEALTH RELEVANCE Label free real time biosensors enable the measurement of the kinetics of biomolecule binding Getting this information earlier in the drug discovery process reduces false positives identifies candidates that may have been missed improves subject matter for patent filings and increases the probability of the selected candidateandapos s eventual success Traditional label free biosensors have limited sample throughput which has restricted their use to secondary roles By combining our highly parallel microfluidic sample delivery technology with a small molecule sensitive biosensor we will enable the high throughput label free analysis of small molecules and biologics which offers significant potential for increasing the efficiency of early stage drug discovery
