in the present study , we compare the different molecular forms of cardiac ( rat heart ventricle ) and vascular ( bovine aorta ) phosphodiesterase isolated from crude extracts prepared either in sucrose medium or in hypotonic medium ( in the presence of protease inhibitors and ion chelators ) using two different fractionation procedures : isoelectric focusing on flat gel bed and deae-trisacryl anion exchange chromatography .
