Reaction characteristics：
Y-shape PEG NHS Ester，Y型聚乙二醇NHS酯是自主研發(fā)的Y型結構，具有2個PEG鏈和一個活性酯基因，可以用來生產(chǎn)蛋白或其他生物分子中的賴氨酸上的氨基進行反應。Y-NHS可以在PH=7-8的緩沖液中在較短的時間內與NH2進行聚乙二醇化。由于Y-NHS具有特殊的空間結構使它更具有選擇性。

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.
