Reaction characteristics:
mPEG-DF是具有胺反應性醛基的單官能位點特定PEG衍生物。醛PEG是一種常見的N端胺基聚乙二醇化試劑。醛基與N端的α-胺之間的反應產(chǎn)生一個中間席夫堿。用氫化物進一步還原將形成穩(wěn)定的C-N鍵。 PEG醛在5.0至9.5的pH下與正端胺基反應。較高的pH將導致末端和賴氨酸基團多次聚乙二醇化。芳香醛PEG在水溶液中顯示出更好的穩(wěn)定性。

Matters for use:
It is sensitive to light and temperature. In order to use the reagent effectively, the material should always be kept in a low temperature dry condition, away from light, and avoid frequent thawing and freezing.
storage conditions:
Store at - 20 ℃ as much as possible. If conditions permit, the material can be treated under?inert gas to obtain better stability of the reagent.
