NH2-PEG2K-Dopamine

NH2-PEG2K-Dopamine can be used to modify proteins,peptides and other materials and small molecules with carboxyl(-COOH)or other active groups that can react with primary amines.Amino(-NH2)can easily form stable amide bond with carboxyl group,and can also form amide bond with active ester(-NHS) in ph7-8.5. Polyethylene glycol can increase solubility and stability.It can also inhibit the non-specific binding of charged molecules on the modified surface.
