Biotin-PEG2-Hydrazide is a flexible bioconjugation reagent that enables selective attachment of biotin to carbonyl-containing biomolecules such as oxidized glycoproteins, carbohydrates, or aldehyde-modified oligonucleotides via hydrazide chemistry. Its PEG2 spacer enhances aqueous solubility and reduces steric hindrance, making it ideal for affinity purification, pull-down assays, and fluorescent labeling workflows in chemical biology research. The compound's strong biotin-streptavidin interaction ensures reliable detection and capture across diverse experimental platforms.
