Patch clamp method developed more than 30 years ago is widely used for investigation of cellular excitability manifested as transmembrane ionic current and/or generation of action potentials. This technique could be applied to measurement of ionic currents flowing through individual (single) ion channels or through the whole assembly of ion channels expressed in the whole cell. Whole cell confi...

Human neurobalstoma cells, SH-SY5Y, are widely studied and data on their electrophysiological characteristics can be found in literature. We used this cell line to set up the whole cell patch-clamp technique, not yet available in our institute, with the goal to make it suitable both for our future scientific projects and for interdisciplinary studies with other research groups. Some instruments...

Abstract Patch clamp recording of neurons is a labor-intensive and time-consuming procedure. Here, we demonstrate tool that fully automatically performs electrophysiological recordings in label-free tissue slices. The automation covers the detection cells images, calibration micropipette movement, approach to cell with pipette, formation whole-cell configuration, recording. based on deep learni...

Short generation times and facile genetic techniques make the fruit fly Drosophila melanogaster an excellent genetic model in fundamental neuroscience research. Ion channels are the basis of all behavior since they mediate neuronal excitability. The first voltage gated ion channel cloned was the Drosophila voltage gated potassium channel Shaker(1,2). Toward understanding the role of ion channel...

The resolution of patch-clamp recordings is limited by the geometrical and electrical properties of patch pipettes. The ideal whole-cell patch pipette has a blunt, cone-shaped tip and a low resistance. The best glasses for making patch pipettes are low noise, low capacitance glasses such as borosilicate and aluminasilicate glasses. Regrettably, nearly all borosilicate glasses form pipettes with...
