ɑ,ω-Bis-Amino PEGs
The amine functional group at each end of the PEG linker molecule allows selective and covalent attachment to other molecules with complementary functional groups, such as carboxylic acids (in the presence of activating agents, i.e. HATU, EDC), activated esters (i.e. NHS Esters), aldehydes and epoxides. The newly formed bonds are amides, imines or secondary amines. Applicable for reversible or permanent crosslinking with PEG.
