Biotin‐PEG4‐NHS Ester Size:100 mg which is the carboxylate ionBiotinPEG4NHS Ester is a pegylated, highly hydrophilic biotinylation reagent for simple and efficient biotin labeling of antibodies, proteins and other primary amine containing biomolecules. BiotinPEG4NHS Ester reacts specifically and efficiently with primary amines (e. g., side chain of lysine residues or aminosilane coated surfaces) at pH 7 9 to form covalent bonds. The hydrophilic polyethylene glycol (PEG) spacer arm of this reagent imparts water
