Comparative competition binding profiles of NPY, PYY, PP, and their derivatives as well as GW1229 against [125I][Leu31,Pro34]PYY binding sites in the presence of 1 μm BIBP3226 in rat brain membrane homogenates. Data represent the mean ± SEM of four to nine determinations, each performed in triplicate and expressed as the percentage of specific binding.
