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(yīng)性PEG衍生物,可用于通過(guò)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(tuán)容易與游離巰基發(fā)生反應(yīng)。
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.
