What is (+)-Biotin-PEG4-Hydrazide?
Description
Biotin-PEG4-hydrazide is a biotinylation reagent that can be used to label glycoproteins, carbohydrate-containing compounds that have oxidizable sugars or aldehydes. Hydrazine moiety reacts with an aldehyde to form semi-permanent hydrazone bonds. The hydrophilic PEG arm imparts water solubility that is transferred to the biotinylated molecule.
