Fmoc-Lys (biotin-PEG12)-OH is a Lysine embedded biotinylation reagent containing a carboxylic group. Reaction of carboxylic with primary amino (-NH2) forms stable, irreversible amide bonds. The Fmoc group can be removed under basic condition to obtain the free amine which can be used for further conjugations. The hydrophilic PEG spacer arm imparts water solubility that is transferred to the biotinylated molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
