8-Arm-PEG-NH2

8-Arm primary amine-functionalized discrete poly(ethylene glycol) (8-Arm-PEG-NH2) is an 8-arm precision PEG derivative. The PEG arms present terminal primary amine groups. Discrete chain lengths with different degrees of polymerization are available. The primary amine can react with activated carboxyl groups or NHS esters to form amide bonds and introduce carboxyl-containing functional moieties. The multiarm structure provides attachment sites for multivalent ligand display or network construction. Arm number, chain length, and functional-group equivalents can be varied to compare crosslink spacing and molecular presentation. In this series, n denotes the number of ethylene glycol repeat units in each PEG arm.

Applications:

Eight-arm PEG multivalent conjugation;
Branched PEG construction;
Crosslinking and site-density studies;
Amide-based bioconjugation;
Peptide and functional small-molecule conjugation.

Customization available.
