Figure 4From: Prolonged morphine administration alters protein expression in the rat myocardiumEffect of morphine withdrawal on the levels of cytoprotective proteins. Myocardial preparations (50 μg proteins) from control rats (CON) and morphine-treated (MOR/W) rats kept drug-free for 3 days after the last dose were resolved by SDS-PAGE, transferred to nitrocellulose membrane and probed with indicated antibodies. β-Actin was used as an internal standard.Back to article page
