A novel labeling approach with good compatibility based on 2-(4-isothiocyanatobenzyl)-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (p-SCN-Bn-DOTA) was established. The labeling conditions of p-SCN-Bn-DOTA with standard peptides were optimized, and the labeling efficiency of macrocyclic complex of p-SCN-Bn-DOTA with lanthanide metal ion Eu(Ⅲ) was also investigated. The labeling process was a two-step reaction. The labeling efficiency was affected by several factors including pH, buffer, reaction time, reaction temperature, and ratio of p-SCN-Bn-DOTA to peptide. The optimized conditions were as followed:the first step of labeling reaction was reacted in 0.2 mol/L triethylene diamine (TEAB) (pH 8.5) buffer for 60 min at 60℃, and the molar ratio of p-SCN-Bn-DOTA with peptide was 32. The second step of rare earth metal chelating was in pH 4.0 HCl/NaAC buffer for 60 min at 60℃. This approach was successfully applied in RGD peptide labeling.
