DNP-dPEG®12-NHS ester, product number QBD-10399, is a medium-length (40 atoms), single molecular weight, discrete polyethylene glycol (dPEG®) linker functionalized on one end with the fluorescent hapten 2,4-dinitrophenol and the N-hydroxysuccinimidyl (NHS) ester of propionic acid on the other end. The NHS ester reacts with free amines to form stable amide bonds. The DNP end of the molecule may be used as a hapten in the development of vaccines or immunotherapeutic applications.

| Typical solubility properties (for additional information contact Customer Support) | Methylene chloride, Acetontrile, DMAC, DMSO or water. |
| Storage and handling | -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. |
