Specific anti-E-selectin targeted fluorescent signal co-registered with X-ray imaging. Following injection of either anti-E-selectin or anti-DNP (control) antibodies labelled with Dylight 750 nm NIR fluorophore (Thermo Fisher Scientific Inc., Rockford, IL, USA) at a dose of 5 μg i.v., paw swelling was induced by intraplantar injection of murine TNF-α into the right paw (RP) in C57/BL6 mice (marked by arrows) (n = 4 to 6). Mean fluorescence signal (MFI) quantified at the 8 h time point is shown for different groups of mice. The mean background intensity from control and anti-E-selectin-targeted animals was subtracted. In the left-hand panel, the corresponding fluorescent image overlaid onto a co-registered X-ray. The colour wheel to depict signal intensity has been adjusted to the range as shown on the graph.
