Characterization of biophysical properties of single chloride channel in rat brain mitochondrial inner membrane by channel incorporation into bilayer lipid membrane
Introduction: Recent studies have shown the presence of Cl- channels in heart and liver mitochondrial membranes. In this work, we have characterized the functional profile of a Cl- channel from rat brain mitochondria. Methods: After removing and homogenizing the rat brain, the supernatant was separately centrifuged in MSEdigitonin, H2O and Na2CO3 and mitochondrial inner membrane vesicles wer...
متن کاملEvidences for a new cation channel in the brain mitochondrial inner membrane
Introduction: Previous studies and our works have indicated several cation channels in the rat brain mitochondrial inner membrane. In this work, we report the single-channel characterization of a cation channel from the rat brain mitochondrial inner membrane incorporated into a planar lipid bilayer. Methods: After removing and homogenizing the adult rat brain, its supernatant was centrifuged...
متن کاملAn evidence for a potassium channel in endoplasmic reticulum based on single channel recording in bilayer lipid membrane
Introduction Numerous studies have demonstrated the presence of potassium selective channels in membranes internal organelles. These channels are essential to a large variety of cellular processes including intracellular 2+ a signaling, protein recycling, charge neutralization and cell protection. In contrast to the sarcoplasmic reticulum + here potassium channels have been clearly ...
متن کاملBiophysical and electropharmacological properties of single mitoKATP channel in rat brain mitochondrial inner membrane
Introduction: Different ATP-sensitive potassium channels have been detected in the mitochondrial inner membrane of cells. They are suggested to be involved in cell processes including cell protection. Here, we characterized the biophysical and electropharmacological properties of a KATP channel in the brain mitochondrial inner membranes. Methods: After removing and homogenizing the rat brain...
متن کاملElectrochemical studies of blocking properties of solid supported tethered lipid membranes on gold.
The insulating properties of self-assembled thiolipid monolayers and tethered lipid bilayers on polycrystalline gold electrodes were studied by means of cyclic voltammetry (CV). These films were formed by two-step self-assembly processes. Electrochemical measurements of the heterogeneous electron transfer rate constant of different redox couples such as potassium ferrocyanide (K(4)[Fe(CN)(6)]) ...
