The mol. self-organization and structural properties of peptide assemblies at different interfaces, using either amphipathic or hydrophobic polypeptide helixes, is described. The two peptides under investigation form stable monolayers on the water surface ...
G protein-coupled receptors (GPCRs) constitute an abundant family of membrane receptors of high pharmacol. interest. Cell-based assays are the predominant means of assessing GPCR activation, but are limited by their inherent complexity. Functional mol. ass ...
Regioselectivity addressable functionalised templates (RAFT) represent topological cyclic peptides containing orthogonally protected attachment sites pointing to opposite faces of the template backbone. Functionalisation of the template with coordinating g ...
We present a simple technique to precisely and continuously adjust the resonance wavelengths of long-period cladding-mode-coupled gratings without strongly affecting the coupling strength. The main principle of this method is based on the strong dependence ...
The surface attachment and detection of DNA probes are essential in the design of nucleic acid-based biosensors. A new strategy for the covalent immobilization of single-stranded oligonucleotides on gold-covered planar supports is presented. Optimization o ...
Ligand binding to the nicotinic acetylcholine receptor is studied by surface plasmon resonance. Biotinylated bungarotoxin, immobilized on a streptavidin-coated gold film, binds nicotinic acetylcholine receptor both in detergent-solubilized and in lipid ves ...
A new strategy for the reversible formation of supported lipid bilayers is introduced. It uses an extension of immobilized metal ion affinity chromatog. technol., which depends on the reversible formation of complexes between metal ion binding chelator gro ...
The nicotinic acetylcholine receptor from Torpedo was immobilised in tethered membranes. Surface plasmon resonance was used to quantify the binding of ligands and antibodies to the receptor. The orientation and structural integrity of the surface-reconstit ...
The reversible, oriented immobilization of proteins on solid surfaces is a prerequisite for the investigation of mol. interactions and the controlled formation of supramol. assemblies. This paper describes a generally applicable method using a synthetic ch ...
The authors probed the function of receptor protein OmpF by in situ measurement of both the binding of ligands by surface plasmon resonance (SPR) and subsequent changes of the channel activity by impedance spectroscopy (IS). [on SciFinder (R)] ...
