生物活性

产品描述	Biotin-PEG4-amine is a biotinylated PEGylated amine linker that provides a flexible spacer suitable for PROTAC synthesis and bioconjugation workflows. Biotin-PEG4-amine facilitates efficient ligand attachment to proteins or small molecules via its terminal amine while preserving accessibility for streptavidin-based detection or enrichment techniques.
体外活性	PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1].
别名	生物素-四聚乙二醇-胺
