Figure 1From: Prolonged morphine administration alters protein expression in the rat myocardiumDistribution of marker proteins in fractionated samples of cardiac tissue. Protein samples (30 μg) of the postnuclear supernatant (PNS), cytosolic (CS), plasma membrane-enriched (PM) and mitochondrial (MT) fractions were subjected to immunoblotting with antibodies against lactate dehydrogenase (LDH), the α subunit of Na, K-ATPase, and F1-ATPase.Back to article page
