Biotin-PEG3-propionic acid Chemical Properties, Uses, Production
Description
Biotin-PEG3-acid is a biotinylation reagent that can react with amine attached molecule. PEG attached to the biotin gives an extended spacer arm that permits the biotin to reach into the binding pocket of the protein or macromolecule.
Uses
Biotin-PEG3-acid is a biotin-labeled, PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
