Biotin-PEG12-Hydrazide

Biotin-PEG12-Hydrazide

This product is a high-purity heterobifunctional PEG linker featuring a biotin moiety on one end and a reactive hydrazide group on the other. The PEG12 spacer enhances hydrophilicity, improves solubility, and reduces steric hindrance, specifically enabling efficient conjugation in both aqueous and organic environments.

Key Features

• Biotin for strong and specific avidin/streptavidin binding

• Hydrazide group for selective coupling with aldehydes and ketones

• PEG12 spacer improves flexibility and solubility

• High chemical stability and purity

Applications

• Biotin labeling of biomolecules

• Protein, peptide, and glycan conjugation

• Antibody–drug conjugates (ADC)

• Surface and nanoparticle functionalization

Storage and Handling

• Store at –20 °C, protected from light and moisture

• Bring to room temperature before use

• Avoid repeated freeze–thaw cycles

This product has a biotin group for strong avidin/streptavidin binding and a hydrazide for aldehyde/ketone coupling, with a PEG12 spacer specifically for solubility and flexibility.
