Farfield Group Press Releases

01 Oct 2004 - New AnaLight® instrumentation range for real time, sub-atomic measurement of biomolecular interactions.

Farfield Sensors Ltd (UK) announces the launch of an expanded range of its AnaLight® instrumentation. The new AnaLight® product series brings Farfield's Dual Polarisation Interferometry (DPI) technology into instrument formats to suit all customer applications and budgets.

The AnaLight® Quantum is an entry-level instrument which enables multi-user research and academic facilities to access DPI technology. The AnaLight® Bio200 is a three-channel instrument for method development and structure-function studies. The AnaLight® Flex is an automated execution platform for structure-function studies, introduced to meet the requirements of the discovery and development facilities with a need for sample throughput.

"Our technology was recently described by one of our customers as a hybrid of X-ray crystallography and biosensors," stated Simon Carrington, Farfields' Marketing Director, "and to some extent it's true. Being real time, it gives more interaction information than X-ray crystallography. By measuring molecular size and density, which is a direct measure of how tightly folded the molecule is, it provides structural information than can not be obtained by using even the best biosensor technologies. As such we fill a unique gap in the market bridging structural and functional analysis. The AnaLight® range is designed with the needs of the end-user in mind. All of our instruments are simple to use in a convenient benchtop format, high-performance, economical, dependable, durable and accurate."

DPI is an exciting analytical technique with the exquisite sensitivity to give previously unavailable insights into the study of structural changes taking place in molecular systems as they function and interact. DPI provides real-time measurements at sub-atomic resolution of molecular size, density and mass, revealing molecular function without recourse to tagging. AnaLight® instruments are quantitative analytical tools, not sensors. Data generated on any AnaLight® instrument is absolute. In simple terms, AnaLight® instruments are 'molecular microscopes' whose quantitative structural measurements can be compared directly with complimentary techniques such as NMR, x-ray crystallography and neutron reflection, whilst also being capable of kinetic measurement at far higher sensitivity and with less ambiguity than biosensor technologies such as SPR or QCM.

Farfield supplies the complete package from instrument through analysis software to sensor chips, comprehensively supported worldwide.
