Fig. 2From: Structural studies on radiopharmaceutical DOTA-minigastrin analogue (CP04) complexes and their interaction with CCK2 receptorThe overlay of the 1H-1H TOCSY (blue) and ROESY (red) spectra of Ga3+-CP04 complex (upper spectra) and Lu3+-CP04 complex (lower spectra). The red spots with no blue ones below indicate ROESY correlations between distinct amino acidsBack to article page
