Properties

Description

Biotin-PEG4-hydrazide serves as a biotinylation agent suitable for labeling glycoproteins and carbohydrate-containing compounds that possess oxidizable sugars or aldehydes. The hydrazine moiety reacts with aldehydes to create semi-permanent hydrazone bonds. Additionally, the hydrophilic PEG arm enhances water solubility, which is transferred to the biotinylated compound.
