mPEG-Biotin (mPEG-Bio, Methoxy PEG Biotin, Methoxypoly(ethylene glycol) Biotin) is a molecule that combines a polyethylene glycol (PEG) chain with a biotin moiety. The methoxy polyethylene glycol (mPEG) chain enhances the solubility of mPEG-Biotin in aqueous solutions. It also provides steric hindrance, which can improve stability and reduce non-specific interactions in biological environments. mPEG-Biotin is often used as a linker or spacer molecule for biotinylated compounds. The biotin group enables specific binding to streptavidin or avidin, while the PEG chain can improve the flexibility and accessibility of the biotin for interactions with its target.
