The invention relates to a functionalized, polymer-reinforced (sterically stabilized) vesicle which comprises a biol., biochem. or synthetic identifying element for identifying and binding a ligand. In addn., the inventive vesicle optionally contains label ...
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 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)] ...
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 ...
Tumor necrosis factor TNF can trigger increases in membrane conductance of mammalian cells in a receptor-independent manner via its lectin-like domain. A lectin-deficient TNF mutant, lacking this activity, was able to bind to artificial liposomes in a pH-d ...
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 ...
Rhodopsin-transducin coupling was used as an assay to investigate a laterally patterned membrane reconstituted with a receptor and its G protein. It served as a model system to show the feasibility to immobilize G protein-coupled receptors on solid support ...
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 ...
The controlled incorporation of polypeptides and proteins into micropatterened lipid mono- and bilayers on solid supports provide important understanding of the structural organization of membrane components and have potential applications in such fields a ...
