      • Overview
        • Amino-dPEG®24-amido-dPEG®24-acid, product number 11305, is a PEGylated amino acid that is useful for many, varied applications. Applications that may be improved by this product include peptide synthesis, surface modification, oligonucleotide sequencing, and small molecule modification.


          The molecule contains a primary amine and a propionic acid group on opposite ends of a single molecular weight polyethylene glycol (PEG) spacer with a discrete chain length. The discrete PEG (dPEG®) spacer consists of two dPEG®24 chains joined via an amide bond in the middle of the chain. The total length of the dPEG® spacer is 152 atoms, which is a distance 178.9 Å. The highly hydrophilic, discrete PEG spacer (Ð = 1) imparts water solubility to conjugates that incorporate it. It is also soluble in many organic solvents.
