Overview

Amino-dPEG4-acid has a primary amine and propionic acid terminating opposite ends of a 16-atoms long (18.0 Å) polyethylene glycol (PEG) spacer. The single molecular weight PEG spacer is discrete (Ð = 1). Moreover, it is highly hydrophilic, and it imparts hydrophilicity to conjugates that incorporate it. Amino-dPEG4-acid is useful in many different applications, including peptide synthesis, surface modification, dendrimer construction, and small molecule modification
