(a) Peptide sequence and schematic molecular structure of CH1055-4Glu-AE105; (b) analytical HPLC of purified probe; (c) MALDI-TOF mass spectrum of CH1055-4Glu-AE105; (d) affinity to the uPAR receptor for the NIR-II labeled peptide (CH1055-4Glu-AE105) and the nonlabeled peptide (AE105); (e) absorbance and fluorescent emission of CH1055, demonstrating an absorbance peak at ∼750 nm and an emission peak at ∼1055 nm. The fluorescent emission spectrum was obtained with an 808 nm excitation laser.
