Figure 2 Anti-glucose transporter 4 immunoblot (top) with matching coomassie blue stained gel (bottom) from patients with hibernating myocardium plus in donor myocardium. Immunoblots from diabetic patients are denoted D. Molecular weight standards are shown in the left lane of the gel. Densitometric quantification of the glucose transporter 4 immunoblot was normalized for myosin heavy chain content using the band at 200 kDa on the Coomassie blue stained gel.
