Applications

Biotin-PEG12-NHS ester is ideal for labeling proteins, peptides, antibodies, and other amine-containing biomolecules. The NHS ester moiety enables selective coupling reactions with primary amines under mild conditions (pH 7-9), resulting in stable amide bonds. The hydrophilic PEG12 spacer enhances solubility in aqueous environments, facilitating efficient conjugation and minimizing nonspecific binding.
