Biotin-PEG2-Hydrazide is a chemical compound consisting of biotin linked to a short polyethylene glycol (PEG) spacer of 2 units, terminating with a hydrazide functional group. One of the key applications of biotin-PEG2-hydrazide is in labeling glycoproteins. The hydrazide group reacts with the aldehyde groups generated by periodate oxidation of glycoproteins, enabling specific and site-selective labeling of glycoproteins with biotin. Biotin-PEG2-hydrazide is also useful in protein modification and engineering. The hydrazide group can react with aldehyde or ketone groups introduced onto proteins, enabling the site-specific conjugation of biotin or other functional molecules for various research or therapeutic purposes.
