From: Prolonged morphine administration alters protein expression in the rat myocardium
Immunoblot analysis of cytoprotective proteins in myocardial preparations from rats affected by morphine exposure. Samples from control (CON) and morphine-treated (MOR) rats were resolved by SDS-PAGE, transferred to nitrocellulose membrane and probed with indicated antibodies. All lanes were loaded with 50 μg proteins. The relative levels of ORP150, hypoxia up-regulated protein 1 (A), HSP27, heat shock protein beta-1 (B), HSC70, heat shock cognate 71 kDa protein (C) and GRP78, 78 kDa glucose-regulated protein (C) were assessed by scanning densitometry.
