biotinpeg4acid

Biotin-PEG4-acid is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.

N-(Amino-PEG4)-N-Biotin-PEG4-acid is a PEG-based PROTAC linker that incorporates biotin for labeling purposes. This compound serves as a versatile tool in the synthesis of PROTACs[1].
