Alexafluor-647 BSA vasculature tracer dynamics. a Fluorescent images during the course of Alexafluor-647 BSA injection. b Mean gray value (MGV) quantification of the Alexafluo-647 BSA injection (0 s corresponds to the time when Alexafluor-647 BSA was administered via tail vein cannulation). The signal remains stable for at least 800 s after administration
