应用
异功能交联剂,使含有化合物或生物分子的叠氮化物与伯胺的叠氮化物连接。琥珀酰亚胺基酯基团将优先与伯胺反应形成共价加合物,末端炔烃将通过铜催化的 1,3-偶极环加成点击化学与叠氮化物反应。亲水性的 PEG 间隔基增加了该试剂的水溶性,使末端胺炔更容易修饰含胺的生物分子,例如抗体、蛋白质和肽。PEG 间隔基还通过增加亲水性来减少溶液中存储的修饰蛋白发生聚集。
Description
Heterobifunctional crosslinker enabling the connection of an azide containing compound or biomolecule to one with a primary amine. The succinimidyl ester group will react preferentially with primary amines to form a covalent adduct and the terminal alkyne will react with azides via copper-catalyzed 1,3-dipolar cycloaddition click chemistry. The hydrophilic PEG spacer adds to the water solubility of this reagent, allowing for easy modification amine containing biomolecules such as antibodies, proteins and peptides with the terminal alkyne. The PEG spacer also reduces aggregation of modified proteins stored in solution by adding hydrophilic character.
