Izolacja komórek mięśni gładkich serca i naczyń krwionośnych od dorosłych, młodocianych, larwalnych i embrionalnych danio pręgowanego do badań elektrofizjologicznych

Overview

This protocol outlines a simple and robust method for the acute isolation of viable cardiac and vascular smooth muscle cells from zebrafish (Danio rerio) at various developmental stages for electrophysiological studies. The process ensures high yield and viability of the cells, allowing for detailed analysis of their ion channel properties.
