Quality assessment of biologics: higher order structure analysis using NMR

27 July 2018 | By Bruker

Two webinar sessions will be available on 27 September at 9AM (BST) and 4PM (BST). Select your preferred¬†time slot during registration.¬† The webinar will describe how 2D NMR can offer protein biochemists unprecedented analytical precision. By assigning just one spectrum, users can obtain a unique fingerprint of a protein at…

Breaking old habits: Moving away from commonly used buffers in pharmaceuticals

10 July 2012 | By David Sek, Research Scientist, Pfizer

One of the key factors in stabilising proteins is determining the optimal pH and buffer system to provide adequate solubility and stability. Currently, three buffers, citrate, phosphate and acetate, make up the majority of buffers used in parenteral pharmaceuticals approved by the FDA, but less precedented excipients are certainly available…

Examining receptor activation: New technologies reveal how G protein-coupled receptors recognise ligands and talk to intracellular partners

24 June 2010 | By Thomas P. Sakmar, Laboratory of Molecular Biology & Biochemistry, Rockefeller University

Heptahelical G protein-coupled receptors (GPCRs) are arguably the most important single class of pharmaceutical drug targets in the human genome. According to Overington, of the 266 human targets for approved drugs, a remarkable 27 per cent correspond to rhodopsin-like, or Family A, GPCRs. Despite recent dramatic advances in targeting of…
