to investigate the response of myosin isozyme transition in specialized myocardium to cardiac overload , we examined immunohistochemically the distribution of myosin isozymes in sinus node cells of overloaded canine atria , using the monoclonal antibodies cma19 and hmc14 , which are specific for atrial myosin heavy chain ( alpha-hc ) and ventricular myosin heavy chain ( beta-hc ) , respectively .
