Patch-Clamp

Patch-clamp amplifiers are specialized instruments crucial for electrophysiology research, enabling precise measurement of ionic currents flowing through cell membranes. These amplifiers utilize glass micropipettes to form a tight seal (a "gigaohm seal") with a cell membrane, isolating a small patch for study. This technique allows researchers to investigate ion channel activity, membrane potential, and other electrical properties of cells, contributing significantly to our understanding of cellular signaling, drug mechanisms, and neurological processes. Workflows supported by patch-clamp amplifiers encompass single-channel recording, whole-cell recording, and perforated patch recording, catering to diverse experimental needs. Leading manufacturers in this field include Molecular Devices (Axopatch series), HEKA Elektronik, and Sutter Instrument.

Leading manufacturers in this field include Molecular Devices (Axopatch series), HEKA Elektronik, and Sutter Instrument. Common applications of patch-clamp electrophysiology include studying the effects of pharmaceuticals on ion channels, characterizing the properties of newly discovered ion channels, and investigating the role of ion channels in diseases like cystic fibrosis and epilepsy. This technique is frequently employed in conjunction with other laboratory methods such as fluorescence microscopy, confocal imaging, and drug delivery systems for a comprehensive analysis of cellular behavior. Patch-clamp amplifiers offer unparalleled precision and control, making them indispensable tools for researchers exploring the intricate world of cellular electrophysiology. ALT offers a selection of pre-owned and refurbished patch-clamp amplifiers, each backed by a standard 90-day warranty that can be upgraded to a three-year warranty, along with ALT's lifetime support. Because they're refurbished, patch-clamp amplifiers from ALT are typically priced 50%-80% lower than the cost of new instruments, helping labs stretch their budget further without compromising on quality. - Less
