Nav1.5 is one of the voltage-gated sodium channels. The majority of sodium channels distributed in the heart is Nav1.5. The current mediated by Nav1.5 rapidly depolarizes cardiac myocytes, underlining the electrophysiological mechanism in the upstroke phase (phase 0) of cardiac action potential. Many congenital heart diseases such as Long QT syndrome 3, Brugada syndrome, sick sinus syndrome are caused by Nav1.5 mutation.
PharmaCore Labs provides manual patch clamp human Nav1.5 (hNav1.5) assay to evaluate drug's inhibition or potentiation effect on hNav1.5 channel.
In vitro electrophysiology hNav1.5 assay with manual patch clamp:
|
Assay platform/method |
Conventional patch clamp |
|
Cells used in the assay |
HEK293 hNav1.5 stable cell line |
|
Measured parameters |
Whole cell current of hNav1.5 channels |
|
Test concentrations |
5 doses for IC50 |
|
Data point repeats |
N ≥ 3 for each concentration |
Note: Positive control: 10 μM Amitriptyline is used in the assay to ensure cell quality and normal response.
