Biotin-PEG4-Hydrazide (CAS 756525-97-0) is a biotinylation reagent featuring a hydrazide reactive group and a PEG4 spacer for enhanced water solubility. This TCI product is designed for selective labeling of glycoproteins and other carbonyl-containing biomolecules via hydrazide-aldehyde/ketone conjugation chemistry. It is widely employed in streptavidin-based detection systems, protein interaction studies, and chemical biology applications requiring high-affinity biotin tagging.
