we investigated the importance of sulfation of gastrin or cholecystokinin ( cck ) on influencing their affinity for gastrin or cck receptors by comparing the abilities of sulfated gastrin-17 ( gastrin-17-ii ) , desulfated gastrin-17 ( gastrin-17-i ) , cck-8 and desulfated cck-8 [ des ( so3 ) cck-8 ] to interact with cck or gastrin receptors on guinea pig pancreatic acini .
