Reaction characteristics:

mPEG-DF是具有胺反应性醛基的单官能位点特定PEG衍生物。醛PEG是一种常见的N端胺基聚乙二醇化试剂。醛基与N端的α-胺之间的反应产生一个中间席夫碱。用氢化物进一步还原将形成稳定的C-N键。 PEG醛在5.0至9.5的pH下与正端胺基反应。较高的pH将导致末端和赖氨酸基团多次聚乙二醇化。芳香醛PEG在水溶液中显示出更好的稳定性。

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.
