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.”

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
