Whole-cell and Perforated Patch-clamp Recordings from Acutely-isolated Murine Sino-atrial Node Cells

Whole-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...

Whole Cell Patch-Clamp Recordings from Lobula plate tangential cells in drosophila melanogaster

Patch Clamp Recordings from Embryonic Zebrafish Mauthner Cells

Mauthner cells (M-cells) are large reticulospinal neurons located in the hindbrain of teleost fish. They are key neurons involved in a characteristic behavior known as the C-start or escape response that occurs when the organism perceives a threat. The M-cell has been extensively studied in adult goldfish where it has been shown to receive a wide range of excitatory, inhibitory and neuromodulat...

Whole-cell patch-clamp recordings from identified spinal neurons in the zebrafish embryo.

We describe a preparation for obtaining patch-clamp recordings from identified embryonic spinal cord interneurons, motoneurons and sensory neurons in an in vivo zebrafish preparation. This preparation is used to study the spatial and temporal patterns of spontaneous and touch-evoked electrical activity during the initial development of circuitry in the spinal cord. The combination of these phys...

Whole Cell Patch-Clamp and SH-SY5Y tumor cells

Human neurobalstoma cells, SH-SY5Y, are widely studied and data on their electrophysiological characteristics can be found in literature. We used this cell line to set up the whole cell patch-clamp technique, not yet available in our institute, with the goal to make it suitable both for our future scientific projects and for interdisciplinary studies with other research groups. Some instruments...
