High throughput screening on Nav1.1 using Qube

The voltage-gated sodium channel NaV1.1 is highly expressed in fast spiking interneurons (FSIs), which are important for memory encoding and other cognitive functions. An impaired function of FSIs is associated with disorders like autism, schizophrenia, Alzheimer’s and others. Potentiators of NaV1.1 have been shown to minimize cognitive dysfunction in transgenic mice with decreased levels of NaV1.1 in parvalbumin-positive neurons and this target thus lend itself to therapeutic intervention. The challenge is to identify the molecule with the desired mode-of-action which inherently requires electrophysiology. In summary we show that Qube 384 provides:

  • Success rates up to 97%
  • Stable, unattended measurements over 7 hours
  • Consistent current voltage relationship
  • High reliability of detecting NaV1.1 activators
