dPEG®12 biotin acid, product number QBD-10197, is a biotinylation reagent containing a single molecular weight polyethylene glycol (PEG) spacer containing biotin on one end and a propionic acid moiety on the other. The terminal propionic acid group couples to amines directly using a carbodiimide such as EDC, and it can be functionalized as an N-hydroxysuccinimidyl (NHS) or 2,3,5,6-tetrafluorophenyl (TFP) ester for reaction with amines.
Amphiphilic dPEG®12 biotin acid can be dissolved both in water or aqueous buffer and in organic solvents. When used as a label, it does not cause aggregation or precipitation of biomolecules even when excess label is used. Using 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) chemistry, QBD-10197 can be coupled directly to free primary amines in aqueous media. These free amines can be on a protein, peptide, or the treated surface of a nanoparticle. The linker length of dPEG®12 biotin acid is longer than the linker length of LC-biotin and longer than the linker length of LC-LC-biotin. The performance characteristics of dPEG®12-biotin acid are quite superior to both LC-biotin and LC-LC-biotin.
Product number QBD-10197 is the precursor product of our popular products QBD-10198, NHS-dPEG®12-biotin, and QBD-10008, Biotin-dPEG®12-TFP ester. Many applications use this product to take advantage of the strong avidin-biotin binding interaction. Such applications include single-cell imaging of protein secretion, developing biosensors, isolating specific cell types by separation with magnetic beads, characterizing and understanding the streptavidin-biotin interaction, creating affinity-based probes, and assembling supramolecular nanostructures.

| Shipping | Ambient |
| 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. |
