Biotin-PEG11-amine结合了生物素(Biotin)、十一聚乙二醇(PEG11)和氨基(Amine)三种成分。Biotin-PEG11-amine可以是固体或粉末状,溶于大部分有机溶剂(如氯仿、DMSO、二氯甲烷等)和水。它具有良好的生物相容性,分子量较大且不易被酶降解。Biotin-PEG11-amine可以与荧光染料、磁性纳米粒子等结合,实现对细胞或生物分子的可视化追踪和表征。
endo-BCN-PEG2-amine的结构中含有BCN(内端硼烷环辛二烯)和胺基的杂双功能PEG连接物。PEG2表示该化合物含有两个乙二醇单元,这使得它具有良好的水溶性和生物相容性。其末端连接的氨基基团(NH2)则赋予了该化合物与多种化学反应基团发生反应的能力,无论是亲核基团还是亲电基团,都能够与之形成稳定的化学键。
