For the functional analysis of ion channel activity, an artificial lipid bilayer suspended over microwells was formed that ruptured giant unilamellar vesicles on a Si substrate. Ca(2+) ion indicators (fluo-4) were confined in the microwells by sealing the microwells with a lipid bilayer. An over...
This analysis demonstrated that slow potential changes during the interburst period were attributable to modifications of ion channels or transporters by intracellular ions and/or metabolites to different degrees depending on [G]. The predominant role of adenosine triphosphate-sensitive K(+) current in ...
Final Ca2 þ concentrations in the media were measured after anaerobic sampling (sealed blood gas syringes were completely filled under an CO2 atmosphere and sealed with caps to avoid loss of CO2) with ABL 730 (Radiometer) by the potentiometric measuring principle, which uses an ion-selective ...
Fluo-5N and rhod-5N dyes were excited with a 488 nm Ar-ion laser and 543 nm HeNe laser, respectively, and the emission was filtered using the Olympus spectra detector. In 3D imaging for reconstructing the fibre structure, the pinhole was adjusted to 0.7 airy units and each confocal section...
Investigations of structural defects and their associated impact on the optical properties of optical materials are essential expediencies because different methods are involved in the preparation of those materials for display applications. Lanthanide ion doping is a simple structural probing strategy that...
The minimal K+ channel protein (minK, also called IsK) is structurally dissimilar to other cloned voltage-gated ion channels. minK is a 15-kD polypeptide w... LC Freeman,RS Kass - 《Circulation Research》 被引量: 144发表: 1993年 Effects of hydrogen peroxide on action potentials and intracel...
Semiconductor nanocrystals (NCs) or quantum dots (QDs) are luminous point emitters increasingly being used to tag and track biomolecules in biological/biomedical imaging. However, their intracellular use as highlighters of single-molecule localization and nanobiosensors reporting ion microdomains changes has...
Ryanodine receptors (RyR) are ion channels responsible for the release of Ca2+ from the sarco/endoplasmic reticulum and play a crucial role in the precise control of Ca2+ concentration in the cytosol. The detailed permeation mechanism of Ca2+ through RyR
These allosteric interactions are key in generating a wide dynamic range for ligand activation of channels and transporters, in addition to linking multiple stimulus modalities to gate ion flux. Although allosteric interactions in the RCK domains have been described in functional terms, the structural ...
