Calcium binding in chemically skinned fibers of rat myocardium during force development.

V I Veksler.   

Abstract

The amount of bound calcium and force were measured in chemically skinned rat myocardial fibers during isometric contraction at different concentrations of free Ca2+. The data obtained suggest that calcium binding by cardiac myofibrils is cooperative and probably depends on mechanical tension.
