Amino-dPEG®4-acid, product number 10244, is an amino PEG acid. A primary amine and propionic acid terminate the ends of the polyethylene glycol (PEG) spacer. The single molecular weight PEG spacer is discrete (Ð = 1). Moreover, it is highly hydrophilic. Consequently, it imparts hydrophilicity to conjugates that incorporate it. Furthermore, Amino-dPEG®4-acid is useful in many different applications, including peptide synthesis, surface modification, dendrimer construction, and small molecule modification.

Discrete PEGylation Reagents

Discrete PEG products (sold under the dPEG® trade name) are a unique class of PEG products invented and manufactured by Quanta BioDesign. Our dPEG® products permit unparalleled control over product development that incorporates PEG linkers and spacers because our products have no dispersity. A complete answer to the question “What is dPEG®?” can be found here. Answers to our most frequently asked questions are on this page.

Using Amino-dPEG®4-acid

There are several advantages to using Amino-dPEG®4-acid. The major advantages of using this product include the following:

  • Non-disperse; there is only one length and molecular weight of PEG in the product;
  • Easily characterized, highly pure product;
  • Imparts water solubility to conjugate molecules;
  • Increases the hydrodynamic volume of conjugate molecules;
  • Improves the flexibility of molecules that incorporate Amino-dPEG®4-acid into the backbone structure (g., a peptide-PEG construct);
  • Non-antigenic/non-immunogenic;

Both ends of the molecule are available for conjugation. Conjugation of only one end of the dPEG® spacer may modify the overall charge of the conjugate. Many different types of coupling reactions are effective for this purpose. However, care should be taken not to use single-step EDC coupling, as this will polymerize the dPEG® product.

In the scientific literature, this product has been used to modify diverse compounds including protein microarrays, biological molecules such as antibodies, RGD dimers, and labeled nucleotides. In each case, amino-dPEG®4-acid was shown to improve sensitivity by increasing the signal-to-noise ratio, reducing non-specific binding, or both.

Amino-dPEG®4-acid is part of a large family of amino PEG acid reagents. To see the complete list, please click this link.
