title: Selective light microscopic demonstration of the specific granulation of the rat atrial myocardium by lead-hematoxylin-tartrazine.
abstract: MacConaill's lead-hematoxylin as modified by Solcia et al. was found to be a highly selective stain for the specific granulation of atrial cardiocytes in the rat. The specific atrial granules were stained blue-black. Contrast was enhanced by counterstaining in a saturated solution of tartrazine in Cellosolve. The stain is compatible with several fixatives and may be used with paraffin or Epon-embedded material.
