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.
