The concentration of peptide-Sumo-mCherry complex (4.0 ±1.4 μg/g of tissue) were significantly increased in the ischemic left ventricle (LV) compared to other organ tissues (non-ischemic LV, right ventricle (RV), lung, liver, spleen, skeletal muscle, and brain) with a p<0.001 (indicated with *). N=6 per group in three independent mice.
