hERG (Kv11.1) - HEK293 Recombinant Cell line

Catalog #: 60619
Size: 2 vials
Species: Human
Genbank #: NM_000238

hERG (human ether-a-go-go-related gene) encodes the alpha subunit of a potassium ion channel, Kv11.1. It contains six transmembrane α-helices with a re-entrant “poreloop” between the fifth and the sixth transmembrane helices. This ion channel is best known for its contribution to the electrical activity of the heart that coordinates the heart's beating. When this channel's ability to conduct electrical current across the cell membrane is inhibited or compromised, either by application of drugs or by rare mutations, it can result in a potentially fatal disorder called long QT syndrome. A number of clinically successful drugs in the market exhibit the potential to inhibit hERG, and create a concomitant risk of sudden death as a side-effect, which has made hERG inhibition an important off-target that must be avoided during drug development.

Recombinant HEK293 cell line expressing human ERG potassium channel (ether-a-gogo-related gene, also known as KCNH2 or Kv11.1, accession number NM_000238).
ERG, human ether-a-go-go-related gene, ether a go go ERG
Supplied As:
Each vial contains ~1.5 X 10^6 cells in 1 ml of 10% DMSO.
Biological Activity:
The channel has been validated for activity using a fluorescence-based assay that uses thallium influx as a surrogate indicator of potassium ion channel activity coupled with a thallium-sensitive fluorescent dye.
Host Cell line:
Mycoplasma Testing:
The cell line has been screened using the PCR-based VenorGeM® Mycoplasma Detection kit (Sigma-Aldrich) to confirm the absence of Mycoplasma species.
