この混合物を、95℃で20分間加熱した。
2つの標識反応を、2D HPLCに注入した。
第1のステップ:生成物をレオダインマニュアルインジェクターを用いてループに注入し、この生成物を第1のポンプを用いてカラム1を通じて押す。この生成物をループからカラム1へと移し、H2O+0.1TFAで洗浄する。
放射性標識化合物12MBqを、新鮮なヒト血漿2mL中でインキュベートした。試料40μLを、0、1、2、18、24、48および72時間後に採取し、かつMini−UniPrep Filter中に200μL(50%メタノールおよび50%アセトニトリル)を添加した。この溶液を、ボルテックス後に濾過する。濾過した溶液40μLをHPLCにより分析する。
CD1 nu/nuマウスに、5×106のA431細胞を注射した。CCK−2受容体陽性A431細胞1を一方の側腹部に注射し、かつ他方に非特異的対照としてmock細胞を注射した。腫瘍は、約10日後には約80〜120mgの重量に達する。放射性標識ペプチド150〜200kBq(5ピコモル)を、尾静脈に注射した。注射後所定の時点の後に、マウスをCO2窒息により殺した。器官を解剖し、秤量し、かつ放射能を測定した。1g当たりの%注入放射能(%i.A./g)を算出した。この動物実験は、現地の動物愛護委員会によって承認され、かつ国の規則に従って行ったものである。
