TTP LabTech has announced that it has been granted a licence for the application of Resonant Acoustic Profiling technology incorporated in the RAPid 4 instrument in the areas of drug discovery and life sciences by Inverness Medical. RAPid 4 is a flow-based analysis system which reduces the need to purify samples and generates accurate kinetic, affinity and concentration measurements from complex mixtures, such as blood, serum, cell culture supernatants and periplastic extracts. A stand-alone, fully automated platform, RAPid 4 requires minimal user intervention and is controlled via user-friendly software, typically processing an average of 400 samples per day.
