Methylamino-PEG3-azide CAS:1355197-57-7 is a chemical compound that consists of a PEG3 (triethylene glycol) linker, an azide functional group, and a methylamino functional group. It is commonly used as a reagent in bioconjugation and chemical biology research to label biomolecules such as proteins, peptides, and nucleic acids with fluorescent dyes, biotin, or other reporter molecules. The azide group in Methylamino-PEG3-azide can selectively react with alkyne-functionalized probes or biomolecules via click chemistry, which is a highly efficient and bioorthogonal conjugation method. The PEG3 linker provides water solubility and flexibility to the conjugated molecules, reducing steric hindrance and improving their bioactivity and stability.
