The CCK-8 analogue, SNF 8702, was radioiodinated. [125I]SNF 8702 showed high-affinity specific binding for both guinea pig and mouse brain tissues, whereas no specific binding was seen for guinea pig pancreatic tissue. The properties of the site labeled by [125I]SNF 8702 were characterized by binding inhibition studies for a series of CCKA and CCKB receptor ligands. The binding selectivity profile corresponded to that for the CCKB receptor. The labeled compound is stable for more than 6 weeks during storage at -20 degrees C.
胆囊收缩素-8类似物SNF 8702进行了放射性碘化。[125I]SNF 8702对豚鼠和小鼠脑组织均显示出高亲和力特异性结合，而豚鼠胰腺组织未见特异性结合。通过对一系列CCKA和CCKB受体配体的结合抑制研究，对[125I]SNF 8702标记位点的特性进行了表征。结合选择性图谱与CCKB受体的图谱一致。标记化合物在-20℃储存期间6周以上保持稳定。
