Alkyne-PEG-NH2 (MW 40000)
Alkyne-PEG-NH2 (MW 40000) is an alkyne-functionalized bifunctional PEG derivative that can be used to modify proteins, peptides, and other materials. The alkyne group reacts with azides in aqueous solution in a copper-catalyzed manner. PEGylation can increase solubility and stability and reduce the immunogenicity of peptides and proteins.
