Mpeg-nhs is one of the monofunctional PEG derivatives. The active ester (NHS) ph7-8.5 reacts with primary amine group to form stable amide bond. Peg functionalized active esters have good water solubility and can be used to modify amino peptides, proteins and other small molecules.
Handling and use：
Attention should be paid to temperature difference and air humidity to prevent moisture absorption. In the reaction as far as possible in the inert gas protection.
Store at - 20 ℃ and keep away from light. Avoid frequent thawing and freezing.
