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(jié)構(gòu)，具有2個(gè)PEG鏈和一個(gè)活性酯基因，可以用來(lái)生產(chǎn)蛋白或其他生物分子中的賴氨酸上的氨基進(jìn)行反應(yīng)。Y-NHS可以在PH=7-8的緩沖液中在較短的時(shí)間內(nèi)與NH2進(jìn)行聚乙二醇化。由于Y-NHS具有特殊的空間結(jié)構(gòu)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.
