Biotin-dPEG?4-hydrazide allows biotin labeling of molecules with free aldehydes or ketones. Biotin-dPEG?4-hydrazide reacts to form a hydrazones. This reagent is highly useful for labeling carbohydrates, glycoproteins, and other molecules with biotin following oxidation of the carbohydrate or glycan with sodium periodate or by chemical installation of an aldehyde or ketone on the target molecule. The dPEG? spacer is a single molecular weight PEG that provides excellent water solubility while extending the biotin moiety away from the surface of the labeled molecule for enhanced binding to avidin or streptavidin.
