Sodium channels
Subgroups:
NaV1.1-1.9

NaV1.5 - Accurate Voltage Control
Port-a-Patch data and applications:
Cells stably transfected with human SCN5A were kindly provided by Millipore.
To perform recordings of fast events, such as the activation and inactivation of Na currents, it is essential to have accurate voltage control. The image shows currents and I/V characteristics of NaV1.5 expressed in HEK293 cells.

Borosilicate glass chips are used as the patch clamp substrate, ensuring excellent voltage clamp of the cell membrane and high quality seals. Voltage gated channels such as hNaV1.5 (HEK293) have been used to validate the system. This data example shows the current-voltage characteristics and the corresponding raw current traces of a single cell from a recording on the SyncroPatch 384PE (a predecessor model of SyncroPatch 384).
