Solubility DMAC, DMSO, acetonitrile, poorly soluble in methylene chloride. Insoluble in water. | |
Spacers dPEG® Spacer is 22 atoms and 27.7 Å | |
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. | |

Biotin-dPEG®₃-Lipoamide
Biotin-dPEG®3-lipoamide, product number QBD-10820, is a water-soluble PEGylation reagent designed to facilitate the biotinylation of a gold, silver, or other metal surface through a short (22 atoms, 27.7 Å) lipoic acid-functionalized single molecular weight, discrete PEG (dPEG®) spacer. The lipoic acid moiety forms dative bonds with gold, silver, and other metals, while the flexible, hydrophilic dPEG® spacer increases the hydrodynamic volume of the conjugate surface. This reduces or eliminates opsonization of the conjugate, contributing to a longer serum circulation time in vivo. Moreover, the water-soluble dPEG® linker improves the hydrophilicity of the biotin label, which is poorly soluble in water, reducing aggregation, precipitation, and non-specific interactions due to hydrophobicity. Potential applications for this product include pull-down assays, affinity chromatography, and biotin-based antibody pretargeting for radioimmunotherapy.
