1)リン酸緩衝アセトニトリル中で等モル量の3NTAおよびMCSを混合し、2〜3時間室温で保温することにより3NTAをMCSにカップリングさせた。3NTA−MCSの特性についてMSにより確認し、化合物をHPLCにより精製した。
2)すべての反応成分が溶けるように固体のグアニジン粉末を加えたリン酸緩衝アセトニトリルを含む溶液中で、等モル量の3NTA−MCSおよび脂質部分を用いて3NTA−MCSと脂質部分の結合を行った。pH6.0と比較してpH7.5で反応効率が大幅に増加したことが分かった。反応生成物の特性についてMSにより確認し、LIPOKEL、LIPOKELP−10、およびLIPOKELP−20をHPLCにより精製した。LIPOKELの質量スペクトルについて質量分析計であるアジレント社シリーズ1100 LC−MSDを使用して決定した。実験による質量3073.95が、推定した質量3074.9Daとほぼ一致した。
