Bright ion channels and lipid bilayers.
If we look at a simple organism such as a zebrafish under a microscope, we would see many cells working in harmony. If we zoomed in, we would observe each unit performing its own tasks in a special aqueous environment isolated from the other units by a lipid bilayer approximately 5 nm thick. These confined units are social: they communicate with one another by sensing and responding to the chem...
متن کاملstudy of cohesive devices in the textbook of english for the students of apsychology by rastegarpour
this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Single-channel electrophysiology of cell-free expressed ion channels by direct incorporation in lipid bilayers.
Single-channel electrophysiology with lipid bilayer systems requires ion channel expression, purification from cell culture, and reconstitution in proteoliposomes for delivery to a planar bilayer. Here we demonstrate that single-channel current measurements of the potassium channels KcsA and hERGS5-S6 can be obtained by direct insertion in interdroplet lipid bilayers from microliters of a cell-...
متن کاملIon transport through channels formed in lipid bilayers by Staphylococcus aureus alpha-toxin.
Staphylotoxin channel appears to be predominantly anion-selective with non-linear and asymmetric current-voltage characteristics (CVC) at neutral pH. Increased salt concentrations induce linearity and asymmetry of CVC and loss of selectivity. At lower pH both the channel conductivity and anion selectivity increase. Higher temperatures raise the channel conductivity in parallel with the changes ...
متن کاملThe synthetic precursor specific region of pre-pro-parathyroid hormone forms ion channels in lipid bilayers.
We have used the chemically synthesized sequence of pre-pro-parathyroid hormone and several of its analogues to test the notion that the capacity of amphipathic peptides to aggregate in membranes and form ion-permeable channels correlates with their ability to function as signal sequences for secreted proteins. We found that pre-pro-parathyroid hormone (the signal sequence and pro-region of par...
