[Description]

Biotin-PEG6-NHS ester is an amine reactive biotinylation reagent that can couple with amino (-NH2) containing molecule. The NHS group reacts specifically and efficiently with lysine and N-terminal amino groups at pH 7-9 to form stable amide bonds. he hydrophilic PEG spacer increases solubility in aqueous media.
[Uses]

Biotin-PEG6-NHS ester is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
