Abstract
【解決手段】 生物学的分析対象物を基材上に捕捉するための方法であって、使用されるリガンドが、ヘム化合物、サイドロフォア、多糖類、及び外膜タンパク質、コンジュゲート脂質や微生物タンパク質標的に特異的なペプチドから成る群から選択され、リガンドは基材の表面から少なくとも15Åの距離にテザーされて、微生物を捕捉する。生物対象物は細菌、ウイルス、リケッチア、原生動物、及び菌類からなる群から選択され、水性試料や医学的試料からの生物学的分析対象物の濃縮のために用いられる。

をテザーしておけば、その末端システイン基によって、特にフリーのStaphylococcus aureus トキシックショック・トキシン−1を捕捉できる。また、次のペプチド、
GHHKHHHGGGC
も、これをテザーしておくことにより、その末端システイン基によって、Staphylococcus aureusの表面に露出しているプロテインAを、よって結局この生物自体を、特異的に捕捉できる。Staphylococcus aureus トキシックショック症候群トキシン−1結合ペプチドについては、A.Satoらによる「ファージディスプレイライブラリーからの、トキシックショック症候群トキシン−1に結合しその主要組織親和性複合体(MHC)クラスII分子との結合を阻害するペプチドの同定(Identification from a Phage Display Library of Peptides that Bind to Toxic Shock Syndrome Toxin−1 and that Inhibit Its Binding to Major Histocompatibility Complex (MHC) Class II Molecules)」(Biochemistry 35、10441−10447(1996))に記載がある。
