HaloTag® リガンドによる最適化されたタンパク質精製と捕捉

プロメガの HaloTag® リガンド製品群は、タンパク質精製におけるアフィニティ標識をはじめとした多様な機能に対応しています。これらのリガンドは、生理的条件下で HaloTag® 融合タンパク質と極めて特異的かつほぼ不可逆的な共有結合を迅速に形成し、安定かつ効率的な標識を可能にします。さらに、バックグラウンドの干渉が最小限に抑えられる点も特長です。HaloTag® リガンドを用いることで、適切な化学基を持つ任意の化合物や表面を対象とした解析が可能になります。また、多彩なHaloTag® Ligand Building Blocksが取り揃えられており、応用の可能性は無限に広がります。

HaloTag® Biotin Ligandは、タンパク質の捕捉および解析において、効率的なビオチン標識を可能にします。このリガンドは細胞膜透過性があるため、細胞内タンパク質に対する標識も可能です。インキュベーション後には、未結合のリガンドを洗い流すことができるため、バックグラウンドを抑えた検出が行えます。

プルダウン性能をさらに高めたい場合には、HaloTag® PEG-Biotin Ligandがおすすめです。このリガンドは、柔軟性の高い長めのスペーサー構造を有しており、ストレプトアビジンとの結合効率が優れています。細胞膜透過性が限られるため、標識には細胞溶解処理が必要ですが、この延長スペーサーによって、固定化や誘導体化の過程において HaloTag® 融合タンパク質の活性が保持されやすいという利点があります

タンパク質精製以外の用途、たとえば、蛍光タグ付きタンパク質を用いた細胞イメージング研究などにも対応した HaloTag® リガンドのラインアップをご用意しています。
