Rational Affinity Devices, LLC delivers cost-effective, technology-based solutions to the life science market through the development of patented innovative, accurate and reliable methods of molecular purification, detection and analysis. The work represents a paradigm shift in methods of detection and processing target molecules through the use of "tunable" affinity ligands A team of inter-disciplinary scientists and partners have designed a unique set of forward-thinking diagnostic products geared to addressing the research and testing needs of the evolving use of biologicals in the marketplace. RADâs approach toward resolution of market needs involves the application of rational design principles to the engineering of molecules with properties amenable to industry, physician and consumer diagnostic products. These principles are being used to develop: the gentlest possible methods for isolating and separating functionally active biological molecules from complex mixtures, and highly quantitative detection methods for ultra-specific molecular, bacterial and cellular analysis. RAD has developed enabling technology to increase both the analytical and biological selectivity of assays designed to discriminate structurally and functionally similar molecules
