Figure 4. Expression of light chain 3 (LC3).
Original Western blots of protein content of LC3 in myocardial biopsies obtained at baseline (BL) before initiation of cardiopulmonary bypass and at 5–10 min reperfusion (R10) from patients undergoing remote ischemic preconditioning (RIPC) or not (placebo). LC3-II (lower band) was normalized to glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and LC3-I (upper band), respectively. Ratios are presented in bar graphs.
