This water soluble alkyne activated ester reagent is used for the attachment of alkyne group to variois biomolecules such as proteins, and peptides. Amino-DNA, and other amines can be used as well. Since natural proteins do not contain alkynes, but almost always contain amines (lysines), this molecule is an “adaptor” to turn natural amines into alkynes.
Use this product to enable any of your proteins for Click Chemistry.
This is an STP (sulfotetrafluorophenyl) ester. STP esters are similar to NHS esters, but possess higher hydrophilicity, and water solubility. It works fine in pure aqueous reactions without addition of organic co-solvent, and is best suited for the modification of proteins.
这种水溶性炔烃活化酯试剂用于将炔烃基团连接到各种生物分子，如蛋白质和肽。 也可以使用氨基-DNA和其他胺。 由于天然蛋白质不含炔烃，但几乎总是含有胺（赖氨酸），这种分子是将天然胺转化为炔烃的“适配器”。
使用此产品可让您的任何蛋白质用于 Click Chemistry。
这是一种 STP（磺基四氟苯基）酯。 STP 酯与 NHS 酯相似，但具有更高的亲水性和水溶性。 它在不添加有机助溶剂的纯水反应中表现良好，最适合蛋白质的修饰。
