Nh2-peg-nh2 is a kind of Ponzi reactive and bifunctional polyethylene glycol derivative containing two primary amine groups on each PEG molecule. Amine groups easily react with succinimide NHS esters, carboxylic acids, aldehydes and many other amine reactive functional groups in aqueous buffers or organic solvents. Due to its good reactivity, PEG diamine is a useful PEGylation reagent, which can modify proteins, peptides, particles 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 PEGylation reactions can be carried out in aqueous buffer.
Nh2-peg-nh2 is sensitive to light and temperature. For best use, the material should always be kept dry at low temperature to avoid frequent thawing and freezing.
