Figure 1.
Representative MSOT images showing the clearance of IRDye800CW from mouse kidneys. IRDye800CW (60 nM dissolved in 0.9% saline) was injected intravenously into WT mice 24 h after sham operation. The clearance/movement of IRDye800CW (green) in the cross section of the right kidney (white square) was recorded. ROIs in cortex and medulla/pelvis region of the kidney are delineated in red and blue, respectively. Representative images of 28 mice (n = 7 in each group). The green bar represents the scale for the mean pixel intensity of the IRDye800CW signal.
