Reaction characteristics：

GA-PEG-GA，聚乙二醇二戊二酸，是一種在分子鏈兩端都含有環(huán)氧基的線性聚合物，是一種PEG試劑。在PEG和羧基COOH基團(tuán)之間存在C4酯連接。GA-PEG-GA可以通過(guò)肽偶聯(lián)劑與氨基反應(yīng)。

GA-PEG-GA的合成通常需要經(jīng)過(guò)一系列的反應(yīng)步驟，包括甘露糖醛酸的活化、與乙二醇的酯化反應(yīng)以及產(chǎn)物分離和純化等。

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.
