Isolierung von hochwertigen atrialen und ventrikulären Myozyten der Maus für die simultane Messung von Ca2+ Transienten und L-Typ Calciumstrom

Overview

This study focuses on isolating high-quality murine atrial and ventricular cardiomyocytes to investigate arrhythmogenesis. By using a retrograde enzyme-based Langendorff perfusion method, the protocol allows the simultaneous measurement of calcium transients and L-type calcium current in isolated cardiac cells.
