Amino-dPEG®₂₄-acid

Amino-dPEG®24-acid, product number QBD-10317, is a PEGylated amino acid. A primary amine group and a propionic acid group sit on opposite ends of a long (76 atoms), single molecular weight polyethylene glycol (PEG) spacer of discrete length (dPEG®). The highly hydrophilic, discrete PEG spacer (Ð = 1) increases the hydrodynamic volume and imparts water solubility to conjugates that incorporate it. Moreover, Amino-dPEG®24-acid benefitted numerous applications, including peptide synthesis, peptide modification, surface modification, oligonucleotide sequencing, drug delivery, and small molecule modification.

Storage Instructions
-20°C; Always let come to room temperature before opening; be careful to limit exposure to moisture and restore under an inert atmosphere; stock solutions can be prepared with dry solvent and kept for several days (freeze when not in use). dPEG® pegylation compounds are generally hygroscopic and should be treated as such. This will be less noticeable with liquids, but the solids will become tacky and difficult to manipulate, if care is not taken to minimize air exposure.
