FIGURE 1 The rapid evolution of sequencing technologies. A. First generation Sanger sequencing technology. B. Second ‘Next’ generation massively parallel sequencing technology (454 Sequencing © Roche Diagnostics) C. Third ‘Next-Next’ generation single molecule, real-time sequencing technology. In the coming years, second or third generation technologies may develop to an extent where a human genome can be sequenced for a USD 1,000 in a matter of hours

DNA sequencing technologies and emerging applications in drug discovery

13 December 2011 | By Nalini A.L. Mehta & David J. Dow, Molecular and Cellular Technologies, Platform Technology and Science, GlaxoSmithKline and Anthony M. Battram, Molecular and Cellular Technologies, Platform Technology and Science, GlaxoSmithKline & Department of Life Sciences, Imperial College London

In recent years, the development of Next Generation DNA Sequencing (NGS) technology has significantly impacted molecular biology research, resulting in many new insights and discoveries. NGS technology goes beyond traditional DNA sequencing with applications that reach across the central dogma of molecular biology from DNA to RNA and protein science.…

FIGURE 1 Structures of active and inactive conformations of the β2 adrenoceptor Structures of the β2 adrenoceptor (light grey) in an inactive conformation with the antagonist carazolol bound (left33), and in an active conformation in complex with Gs (dark grey) and the agonist BI-167107 bound (right41). In both cases, the ligand is represented by black spheres to show the location of the orthosteric binding site within the membrane-spanning region of the protein. T4 lysozyme (black) is inserted in the third intracellular loop between helices 5 and 6 in the inactive structure (bottom left), and fused in the extracellular N-terminus for the active structure (top right), to remove flexibility and to provide polar surfaces for crystallisation. The nanobody (black, bottom right) served to stabilise the open conformation of Gs and also provided crystallisation contacts

Lead discovery for targeting G protein-coupled receptors

19 October 2011 | By Sandra Siehler and Sandra W. Cowan-Jacob, Novartis Institutes for BioMedical Research

G protein-coupled receptors (GPCRs) control a plethora of key physiological functions in every cell of an organism. GPCRs are therefore involved in many diseases, since altered ligand or receptor levels and genetic or epigenetic modifications can lead to GPCR dysfunction and hence a pathophysiological phenotype. About one third of currently…

Stabilisation of nanoparticles during freeze drying: The difference to proteins

31 August 2011 | By Jakob Beirowski and Henning Gieseler, University of Erlangen-Nuremberg, Division of Pharmaceutics, Freeze Drying Focus Group

The underlying concept for the stabilisation of proteins during freeze drying is the formation of a glassy matrix in which the macromolecules remain isolated and immobilised. The concept relies on the so-called ‘vitrification hypothesis’ which assumes that the formation of an amorphous phase by lyoprotectants is mandatory to interact with…
