产品描述:
一种含生物素基团和 4 个 PEG 的 azadibenzocyclooctyne-biotin 衍生物。DBCO-PEG4-Biotin 是一种用途广泛的生物素酰化试剂,能通过无铜催化烷基叠氮化反应 (SPAAC) 将生物素的一部分引入叠氮标记的生物分子中。
DBCO-PEG4-biotin is a PEG derivative containing a biotin group and an alkyne group. The alkyne group can react with azide moiety in copper-free Click Chemistry reaction to form a stable triazole linkage. The hydrophilic PEG spacer increases solubility in aqueous media and increases membrane impermeability of the molecules conjugated to the biotin compound. It also helps to minimize steric hindrance involved with the binding to avidin molecules.
