DNP-PEG3-CH2 NHS Ester
This product is a high-purity heterobifunctional PEG linker featuring a 2,4-dinitrophenyl (DNP) group for antibody or receptor targeting and an NHS ester for efficient coupling with primary amines. The PEG3 spacer specifically provides enhanced solubility, flexibility, and reduced steric hindrance, enabling reliable and reproducible conjugations in both aqueous and organic media.
