(A) Quantification of sarcoplasmic reticulum Ca²⁺-ATPase (SERCA2a) activity in remote, border, and infarct regions of experimental and normal control sheep hearts. (B) Immunoblots from different regions of the myocardium in different groups for SERCA2a and phospholamban. Note that in the infarct region, there was residual myocardium that was homogenized and protein extracted. Abbreviations as in Figures 1 and 2.
