Labeling efficiency and radiochemical purity of the 125I- RGD4CβL. The labeling rate and the radiochemical purity of the 125I-RGD4CβL were determined using radio-thin layer chromatography. (A) The labeling efficiency was calculated to be 86.5%. (B) Following purification, the radiochemical purity of the 25I-RGD4CβL was 100%, which is suitable for the in vivo imaging and the biodistribution assay.
