Cell Electrophysiology

Patch clamp pipettes on mouse DRG cells
Based in San Diego, California, our in vitro cell electrophysiology platform focuses on services with cell recordings (human iPSC-derived neurons, primary rodent neurons, and DRG sensory neurons from rodent/canine/non human primates), building on over 17 years of experience globally with Neuroservices-Alliance in providing pharmacological assays.
These cell electrophysiology services support decision making in CNS or PAIN drug discovery research programs.

Expertise in CNS & PNS cell electrophysiology

Our cell electrophysiology experts have extensive experience in patch clamp and calcium imaging, allowing the determination of molecular effects on neurons and neuronal networks:
  • Cloned channels and receptors
  • Primary neurons (rodent brain)
  • DRG sensory neurons (cyno, nhp, rabbit)
  • iPSC-derived neurons from human donors (healthy or patients)
We can implement protocols tailored to establishing pharmacology, target engagement, Mechanism(s) of Action, and safety issues.
Our cell electrophysiology platform also proposes electrophysiological characterization services of iPSC-derived neurons (proprietary or commercial cell lines).

Our techniques & models

Patch Clamp

Neuroservices-Alliance is a world-renowned leader in patch clamp electrophysiology. Patch Clamp allows in vitro evaluation of compounds under the most physiologically relevant conditions.

Calcium imaging

Calcium imaging provides insight into dynamic changes in calcium levels inside individual neurons. We use ratiometric calcium imaging techniques to focus on validated neurons in co-culture environments.

High Density Multi Electrode Array (HD-MEA)

Thanks to our partnership with Maxwell Biosystems, we use the MaxTwo 6-well High Density MEA recording system. These techniques evaluate features such as global/burst firing as measures of neuronal activity across individual neurons as well as the broader network.
