Fmoc-Lys (biotin-PEG)-OH/N-Boc-Biocytin/PEG-Biotin-PEG

Broad class of PEGylated, water-soluble reagents for simple and efficient biotin labeling of antibodies,

proteins and other primary amine-containing macromolecules. PEGylation imparts water solubility to the

biotinylated molecule, helping to prevent aggregation of biotinylated antibodies stored in solution.

Fmoc-Lys (biotin-PEG)-OHreagents are Lysine embedded biotin PEG derivatives containing a

carboxylic group and Fmoc-protected amine. Reaction of carboxylic with primary amino (-NH2) forms stable,

irreversible amide bonds. The Fmoc group can be deprotected under basic condition to obtain the free amine

which can be used for further conjugations.

N-Boc-Biocytin, this class of biotin PEG derivative contains a carboxylic group and Boc-protected amine.

Reaction of carboxylic with primary amino (-NH2) forms stable, irreversible amide bonds. The Boc group can

be deprotected under acidic condition to obtain the free amine which can be used for further conjugations.

PEG-Biotin-PEG, 3-arm PEGylated biotin PEG derivative that allows reaction with two amine-containing

moiety to form stable, irreversible amide bonds.
