Fig. 1From: Pre-clinical evaluation of eight DOTA coupled gastrin-releasing peptide receptor (GRP-R) ligands for in vivo targeting of receptor-expressing tumorsSchematic representation of BN peptide conjugates DOTA-PEG4-BN. BN sequences are here indicated using the three-letter amino acid code. Substitutions with respect to the wild-type BN[7–14] and addition at the C- or N-terminus are also shownBack to article page
