N3-PEG4-C2-Pfp ester 是一种不可降解的含 4 个单元 PEG 的 linker，可用于合成抗体偶联活性分子 (ADC) 。N3-PEG4-C2-Pfp ester 是一种点击化学试剂。它含有 Azide 基团，可以和含有 Alkyne 基团的分子发生铜催化的叠氮-炔环加成反应（CuAAc)。还可以和含有 DBCO 或 BCN 基团的分子发生菌株促进的炔-叠氮环加成反应 (SPAAC) Azido-PEG4-PFP ester is a PEG derivative containing an azide group and a PFP group. The azide group enables Click Chemistry. The PFP ester is a better leaving group compared to a hydroxyl group and can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The hydrophilic PEG spacer adds to the water solubility of this reagent. N3-PEG4-C2-Pfp ester is a non-degradable 4-unit PEG linker that can be used to synthesize antiboy-coupled active molecules (ADCs). N3-PEG4-C2-Pfp ester is a click chemical. It contains Azide groups and can undergo copper-catalyzed azide-alkyne cycloaddition reactions (CuAAc) with molecules containing Alkyne groups. Strain-promoted acetylene-azide cycloaddition reactions (SPAAC) can also occur with molecules containing DBCO or BCN groups. 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.
