キッコーマンバイオケミファ(株)社製の綿糸を原料とする“ルシパック”Penを使用した。
単糸繊度2.42dtexを含む総繊度84dtexの編物。これを図2のように折り、接合部4を溶着により接着し、袋状とし、それを内外反転させて、あらためて袋状とした。
住鉱潤滑剤(株)社製ミシンオイルTO-M1-Nを200gに対して、和光純薬工業(株)社製アデノシン三リン酸二ナトリウム(ATP結晶)を1mg添加し、ヤマト(株)社製超音波洗浄器サンパW-113にて3分間超音波を発振させて、均一なATP溶液を調製した。
試薬一体型拭き取り綿棒“ルシパック”Penと“ルミテスター”PD-20を使用し、操作はキット添付の方法に準拠して実施した。比較試料の回収部の湿潤方法については、100μLの滅菌精製水をマイクロピペットにて添加した。
PETフィルムシートにマイクロピペットにて20μLのATP溶液を添加し、プラスチック製ディスポーザブルループにて30×30mmの範囲に伸展させた。この部分を滅菌精製水で湿潤させた“ルシパック”Penにて採取し、“ルミテスター”PD-20にてATP値を測定した。“ルシパック”Penにて採取することを5回繰り返し、全てのATP値を合算し、ATP溶液20μLのブランク溶液のATP値とした。
上記の実験を10回繰り返し、平均値を求めた。
PETフィルムシートに、マイクロピペットにて20μLのATP溶液を添加し、プラスチック製ディスポーザブルループにて30×30mmの範囲に伸展させた。この部分を滅菌精製水で湿潤させた試料にて1回のみ採取し、ルミテスターPD-20にてATP値を測定した。四種類の試料で同じ実験を10回繰り返し、それぞれの試料が拭き取ったもののATP値の平均を求めた。試料が付着させたATP溶液のATP値の平均値を、ブランクATP溶液のATP値の平均値で除して、回収率を求めた。
