Nh2-peg-nh2 is a kind of bifunctional polyethylene glycol derivative which contains two primary amine groups in each PEG molecule. Amines react easily with succinimide NHS esters, carboxylic acids, aldehydes and many other amine reactive functional groups in aqueous buffer or organic solvents. Due to its good reactivity, PEG diamine is a useful peg reagent, which can modify proteins, peptides, granules and many other materials. Our diamino PEG derivatives have high purity, narrow molecular weight distribution and a variety of different sizes. These amino peg are easily soluble in water, and all peg reactions can be carried out in aqueous buffer.

Handlingand Use:

Attention NH2-PEG-NH2 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.

Storage condition:

NH2-PEG-NH2 should be stored at -20℃. Desiccate.  Materials may be handled under inert gas for best stability. Re-test material after 12 months.
