Functional ion channel activity can be hindered by prolonged exposure to drugs that inhibit trafficking of the channel protein from cytoplasmic sites to the surface membrane.

HERG-Lite® and CHAN-Lite® are chemiluminescent assays that identify trafficking inhibition in cardiac cell lines following overnight drug exposure.


  • Determine specificity of drug-induced trafficking inhibition
  • Identify compounds that enhance cell-surface expression
  • Rapid results
