Automated planar patch-clamp.
Ion channels are integral membrane proteins that regulate the flow of ions across the plasma membrane and the membranes of intracellular organelles of both excitable and non-excitable cells. Ion channels are vital to a wide variety of biological processes and are prominent components of the nervous system and cardiovascular system, as well as controlling many metabolic functions. Furthermore, i...
متن کاملHTS techniques for patch clamp-based ion channel screening - advances and economy.
INTRODUCTION Ten years ago, the first publication appeared showing patch clamp recordings performed on a planar glass chip instead of using a conventional patch clamp pipette. "Going planar" proved to revolutionize ion channel drug screening as we know it, by allowing high quality measurements of ion channels and their effectors at a higher throughput and at the same time de-skilling the highly...
متن کاملThe patch clamp technique in ion channel research.
To understand the pathogenesis of a given ion channel disorder, knowledge of the mutation alone is insufficient, instead, the description of the associated functional defect is decisive. The patch clamp technique enables to achieve this both in native tissue as well as heterologous expression systems. By this technique, structure-function relationships of ion channels were elucidated that not o...
متن کاملMultichannel incubation type planar patch clamp biosensor using plastic (PMMA) substrates and characterization by laser-gated ion-channel protein
Recently we have developed 4 channel incubation type planar patch clamp biosensor with polymethylmethacrylate (PMMA) substrate by using both-side hot embossing, focused ion beam micro-fabrication and surface modification by extra cellular matrix. We have evaluated the performance by using the light-gated ion-channel protein, channelrhodopsin wide receiver (ChRWR) expressed on HEK293 cell. Obser...
متن کاملMicrofluidic system for planar patch clamp electrode arrays.
We present a microfluidic system integrated with disposable cell interface partitions for simultaneous patch clamp recordings. Glass-supported poly(dimethylsiloxane) (PDMS) partitions, having a 2 microm air-blown aperture, were reversibly sealed to a microfluidic system including PDMS channels with isolation valves and microfabricated Ag/AgCl electrodes. Gigaseal recordings from RBL-1 cells wer...
