Description

Hydrazide-PEG4-Desthiobiotin combines a hydrazide functional group, a PEG4 (polyethylene glycol) spacer, and a desthiobiotin moiety, providing unique advantages in terms of reactivity, flexibility, and reversible binding. The hydrazide group reacts specifically with carbonyl groups, allowing for site-specific labeling of oxidized biomolecules. The desthiobiotin moiety allows for reversible binding to streptavidin or avidin, facilitating gentle purification and recovery of labeled biomolecules. The PEG4 spacer enhances the solubility of the reagent in aqueous solutions and reduces steric hindrance, improving labeling efficiency and preserving biomolecular function. Hydrazide-PEG4-Desthiobiotin is particularly effective for labeling glycoproteins and carbohydrates that have been oxidized to introduce aldehyde groups, allowing for the study of glycosylation patterns and glycan interactions.
