Biotin-PEG2-acid 是一种不可降解 (non-cleavable) 的含 2 个单元 PEG 的 ADC linker，可用于合成抗体偶联活性分子 (ADC)。Biotin-PEG2-acid 是一种 PROTAC linker，属于 PEG 类，可用于合成 PROTAC 分子。 Biotin-PEG2-acid is a heterobiofunctional biotin PEG derivative containing a carboxylic acid group. The hydrophilic PEG spacer arm imparts water solubility that is transferred to the biotinylated molecule. Application： Applicated in medical research, drug-release, nanotechnology and new materials research, cell culture. In the study of ligand, polypeptide synthesis support, a graft polymer compounds, new materials, and polyethylene glycol-modified functional coatings and other aspects of the active compound.
