ProteomeX, Flex Chip Kinetic Analysis System


Thermo Finnigan last week introduced a multidimensional capillary LC/MS system called ProteomeX, based on its LCQ Deca XP ion trap mass spectrometer, Surveyor HPLC, and TurboSequest software. The new instrument is designed for LC/MS/MS proteomics experiments, such as high-throughput protein identification, shotgun sequencing of complex samples, and differential protein quantitation using ICAT reagents.

Bill Hancock, Thermo Finnigan’s VP of proteomics, said, “A researcher can load a sample with peptides from thousands of proteins and, within a matter of hours, know what those proteins are.”


HTS Biosystems has released the beta 2 version of its Flex Chip Kinetic Analysis System. The flexible, label-free detection platform for parallel kinetic analysis of binding events is expected to be the first instrument on the market to provide high-throughput binding kinetics. Gregory Freitag, the company’s CEO, said the system would “revolutionize the way the proteomics industry characterizes molecular interactions.”

HTS says the initial application of the technology is capable of analyzing hundreds to thousands of molecules in a single run. The system employs a plastic, disposable biosensor chip with application-specific surface chemistries. A commercial launch of the product is scheduled for the first half of 2002.
