Thrombin is the final coagulation protease in regard to hemostasis, promoting both procoagulant and anticoagulant effects.
アプリケーション
Thrombin is used for site specific cleavage of recombinant fusion proteins containing an accessible thrombin recognition site for removal of affinity tags. Thrombin has been used in a study to assess an innovative flow cytometric approach for small-size platelet microparticles.
生物化学的／生理学的作用
Arg-Glyを選択的に切断するセリンプロテア-ゼは、フィブリノ-ゲン内に結合し、フィブリンおよびfibrinopeptide A、Bを形成します。
単位の定義
活性は、NIHトロンビンスタンダ-ドとの直接比較によって得られるNIH unitで表しています。
アナリシスノート
NIHのアッセイでは、Biggs法の変法に基づいて、トロンビンサンプル(1%緩衝アルブミン溶液で安定化)0.1 mLと、基質として希釈血漿(同量の生理食塩水で希釈)0.2 mLを用います。凝固時間が15～25秒の範囲のものだけを用いてトロンビン濃度を決定します。
