色々調べるとethanolamineをBSAのようにノンスペを抑えるブロッキングに使う事もあるようですね。

Protein A/G/L Blocking:
Methods to effectively block the Protein A /G/L immunomagnetic beads without introduction of foreign proteins (which might interfere with later analysis) are outlined below:
Protein A immunomagnetic beads: 50 mM Tris, 200 mM glycine, 1% Tween®-20, pH 10,6 treated overnight at RT
Protein G immunomagnetic beads: 50 mM Tris, 200 mM ethanolamine, 1% Tween-20, pH 10,6 treated overnight at 4°C
Protein L immunomagnetic beads: 50 mM Tris, 200 mM ethanolamine, 1% Tween-20, pH 10,6 treated overnight at 4°C
ただクロスリンカーの反応の後に加えるのは主にクロスリンカーを不活性化するためです。 |
