ケーススタディ 4: アプリケーション (XP®モノクローナル抗体)

#4060 Phospho-Akt (Ser473) (D9E) Rabbit mAb

XMT®は、従来のハイブリドーマ技術では成し得なかった様々なB細胞 (抗体産生細胞) の開発を可能にし、より包括的なスクリーニングを可能にしました。CSTの厳格な品質管理とXMT®を組み合わせることにより、様々なアプリケーションで優れたパフォーマンスを発揮するXP®モノクローナル抗体の選別が可能になりました。#4060 Phospho-Akt (Ser473) (D9E) XP® Rabbit mAbを、従来の方法では不可能だったすべてのアプリケーションで優れたパフォーマンスを発揮する一例としてご紹介します (Table 1 参照)。
