The manual patch clamp (MPC) technique has a storied history as a fundamental tool for electrophysiological research since its development in the late 1970s. It is widely used for its unmatched sensitivity and precision, allowing detailed investigation of ion channel behaviors in various cell types. The manual nature of this method provides a level of control and observation that automated patch clamps can't match, particularly when studying complex or rare ion channel pharmacology. This hands-on approach yields high-quality, reproducible data, essential for in-depth functional analyses in drug development and neurophysiological research. Our service harnesses the power of this technique with unmatched expertise, a broad array of targets, and rapid, cost-effective delivery of results.

MPC Assays at Physiological Temperature

In adherence to the updated ICH S7B Q&A requirements, we've expanded our services to include manual patch clamping at physiological temperatures, significantly enhancing the relevance of our data to human cardiac physiology. This approach provides a more accurate prediction of a drug's cardiac safety profile, mirroring in vivo conditions and ensuring the high fidelity of our cardiac ion channel assays. Our physiologically-temperatured assays represent a significant advancement in predicting clinical outcomes.
