Developed by LGC as part of the DTI-funded Measurements for Biotechnology (MfB) programme 2004-2007, this innovative approach is the first DNA-based PT scheme able to provide test materials applicable to a significantly wide range of sectors, beneficial to analysts working in clinical, pharmaceutical, forensic, academic and public health laboratories. LGC has established a reputation for setting up and running successful PT initiatives and, as the UK’s National Measurement Institute for chemical and biochemical analysis, promotes international standards for analytical measurement for use in trade, industry, academia and government.
The new scheme encompasses DNA extraction from a proprietary generic matrix and Q-PCR quantification of extracted samples. Participants will be provided with synthetic analytes and matrices, together with target-specific reagents for real-time PCR quantification. The scheme will support a range of detection chemistries and platforms and will operate in accordance with the principles of ILAC Guide 13 and ISO Guide 43-1.
PT schemes enable laboratories to monitor and improve analytical measurements by providing an external quality assessment system to complement their own internal quality control processes. Participation in a PT scheme is integral to laboratory accreditation and often supports regulatory requirements, such as the UK Environment Agency’s Monitoring Certification Scheme (MCERTS).
On announcing the new scheme, Dr John Marriott, Director of Analytical Technology at LGC, and Government Chemist, said: "As the first cross-sectoral DNA-based PT scheme it is a valuable aid to good quality measurements in the technically difficult field of quantitative DNA analysis. Participation in the scheme will help analysts to pinpoint any area of weakness in their procedures and set-up.”

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
