三、Reaction characteristics：
Vinylsulfone聚乙二醇生物素中（VS）官能化聚乙二醇（VS-PEG）是一種巰基（-SH）反應性PEG衍生物，可用于通過其可用的巰基修飾生物分子或其他材料。室溫下，在pH6.5～8.5的緩沖液中，VS基團容易與游離巰基發(fā)生反應。
Vinyl sulfone (VS) functionalized polyethylene glycol (VS PEG) in vinyl sulfone polyethylene glycol biotin is a reactive PEG derivative of thiol (- SH), which can be used to modify biomolecules or other materials through its available thiol groups. At room temperature, in a buffer solution with pH 6.5-8.5, VS groups are prone to react with free thiol groups.
四、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.
五、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.
