Assay Method Information

Assay Name:  IonWorks Quattro Assay
Description:  CFTR activity can be quantified by electrophysiology methods, using the whole-cell configuration of the patch clamp technique (Hamill O, Marty A, Neher E, Sakmann B and Sigworth F. Improved patch-clamp techniques for high resolution current recording from cells and cell-free membrane patches. Pflugers Archive 1981 391: 85-100). This assay directly measures the currents associated with chloride flow through CFTR channels whilst either maintaining or adjusting the transmembrane voltage. This assay can use either single glass micropipettes or parallel planar arrays to measure CFTR activity from native or recombinant cell systems. Currents measured using parallel planar arrays can be quantified using an appropriately equipped instrument such as the IonWorks Quattro (Molecular Devices Corporation, Sunnyvale, Calif.). The Quattro system can measure CFTR currents from either a single cell per recording well (HT configuration) or alternatively from a population of 64 cells per well (Populatio
