Measurement of cellular excitability by whole cell patch clamp technique.
Patch clamp method developed more than 30 years ago is widely used for investigation of cellular excitability manifested as transmembrane ionic current and/or generation of action potentials. This technique could be applied to measurement of ionic currents flowing through individual (single) ion channels or through the whole assembly of ion channels expressed in the whole cell. Whole cell confi...
متن کاملWhole-Cell Patch-Clamp Recordings
The patch-clamp recording technique, which measures ionic currents under voltage clamp, was designed to study small patches of membranes in which near perfect control of the transmembrane voltage can be achieved readily. The recent application of patch-clamp methodology to the analysis of whole-cell current actually defies many of the original design requirements. Nevertheless, whole-cell recor...

متن کاملVoltage-clamp measurement of visually-evoked conductances with whole-cell patch recordings in primary visual cortex.
Whole cell patch recordings have been realized in the primary visual cortex of the anesthetized and paralyzed cat, in order to better characterize input resistance and time constant of visual cortical cells in vivo. Measurements of conductance changes evoked by visual stimulation were derived from voltage clamp recordings achieved in continuous mode at two or more different subthreshold holding...
متن کاملassessment of potassium current in royan b1 stem cell derived cardiomyocytes by patch-clamp technique
embryonic stem cells are capable of differentiating to variety of cell tissues including cardiomyocytes. this developmental change is accompanied with a great deal of ion channel expression and functions. mouse stem cell derived cardiomyocytes were prepared and separated to yield isolated single cell suspension for cell current recording. in the present study some properties of the k + -current...
