产品使用指南 技术支持

t-Boc-N-Amido-PEG5-Tos 是一种含有甲苯磺酰基和 Boc 保护的胺基的 PEG 连接基。亲水性 PEG 间隔基可增加化合物在水性介质中的水溶性。甲苯磺酰基是亲核取代反应中非常好的离去基团。Boc 基团可在温和酸性条件下脱保护以形成游离胺。

生物活性

t-Boc-N-Amido-PEG5-Tos is a PEG linker containing a tosyl group and Boc-protected amine group. The hydrophilic PEG spacer increases the water solubility of a compound in aqueous media. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The Boc group can be deprotected under mild acidic conditions to form a free amine.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
