Axion's patent-pending Local Extracellular Action Potential (LEAP) assay allows you to record extracellular action potential waveforms, which are stable on the time scale of 10-20+ minutes. The new LEAP assay signal allows quantification of action potential morphology and characterization of complex repolarization irregularities such as early afterdepolarizations (EADs). LEAP is label-free and doesn't disrupt the underlying biology, meaning you can focus on the pharmacology and not on dye-drug or dye-biology interactions.
