Description
1.自己組み立て複合体の製造
超純水に銅クロリド(Copper chloride)、AMP(Adenosine monophosphate)、ATP(Adenosine triphosphate)をそれぞれ溶かして最終濃度が1Mになるように準備する。ストックソリューション(stock solution)をコニカルチューブ(conical tube)に入れ、超純水の量を計算して入れる。ここにアデノシンリン酸塩水溶液、カルシウムイオン水溶液の順に入れ、ボルテックシング(vortexing)してよく混合し、24時間の間反応させる。
前記自己組み立て複合体にアデノシンのような薬物を含有して合成する場合、カルシウムイオンを入れる前にアデノシンを入れて残りの過程を進行する。この後、1と同じ過程で実験を進行し、24時間の間の反応が終了すると、反応していない物質を除去し、自己組み立て体を収得するために、遠心分離機を通して10,000RPMで10分間遠心分離して自己組み立て体を沈め、上清液を除去する。超純水を本来の体積と同一に入れ、また遠心分離する。この過程を2回繰り返す。
