Fig. 6From: Synthesis and In Vitro Study of a Dual-Mode Probe Targeting Integrin αvβ3Cell magnetic resonance and fluorescence imaging. a The cells were incubated with A549 cells for 2 h according to the Gd concentrations: 0, 0.005, 0.01, 0.02, 0.04, and 0.08 (mM). The Gd-Cy5.5 was used as the control group. b T1 relaxation time of the corresponding magnetic resonance image. c Small animal live imaging system imagesBack to article page
