Crystallisation of membrane proteins mediated by antibody fragments.
X-ray structures of three different membrane proteins in complex with antibody fragments have been published. The binding of Fv or Fab fragments enlarges the hydrophilic part of integral membrane proteins, thereby providing additional surface for crystal contacts and space for the detergent micelle. In all reported cases, antibody binding was either essential for the crystallisation of the memb...
متن کاملHigh-throughput expression and purification of membrane proteins.
High-throughput (HT) methodologies have had a tremendous impact on structural biology of soluble proteins. High-resolution structure determination relies on the ability of the macromolecule to form ordered crystals that diffract X-rays. While crystallization remains somewhat empirical, for a given protein, success is proportional to the number of conditions screened and to the number of variant...
متن کاملMembrane-aerated microbioreactor for high-throughput bioprocessing.
A microbioreactor with a volume of microliters is fabricated out of poly(dimethylsiloxane) (PDMS) and glass. Aeration of microbial cultures is through a gas-permeable PDMS membrane. Sensors are integrated for on-line measurement of optical density (OD), dissolved oxygen (DO), and pH. All three parameter measurements are based on optical methods. Optical density is monitored via transmittance me...
متن کاملDevelopment of a pipeline for automated, high-throughput analysis of paraspeckle proteins reveals specific roles for importin α proteins
We developed a large-scale, unbiased analysis method to measure how functional variations in importin (IMP) α2, IMPα4 and IMPα6 each influence PSPC1 and SFPQ nuclear accumulation and their localization to paraspeckles. This addresses the hypothesis that individual IMP protein activities determine cargo nuclear access to influence cell fate outcomes. We previously demonstrated that modulating IM...
متن کاملSurface plasmon resonance for high-throughput ligand screening of membrane-bound proteins.
Technologies based on surface plasmon resonance (SPR) have allowed rapid, label-free characterization of protein-protein and protein-small molecule interactions. SPR has become the gold standard in industrial and academic settings, in which the interaction between a pair of soluble binding partners is characterized in detail or a library of molecules is screened for binding against a single sol...
