Based on its proprietary fluorescence cross correlation spectroscopy (FCCS) Intana offers highly-specific biochemical profiling services for companies in the pharmaceutical, chemical and life science industries. FCCS is an interaction analysis based on a single molecule sensitive spectroscopic approach. The technology is extremely well suited to characterize molecular interactions between active ingredients, targets and off targets in cellular lysates. So far, the technology has been successfully employed for customers from the pharmaceutical industry in their drug discovery and development efforts. FCCS can be employed as an efficient tool to determine dissociation- and rate constants.
