QUICK LINKS

Biotin-PEG11-Amine represents a specialized chemical linker utilized extensively in the realm of biochemical and molecular biology research, serving as a bridge to covalently attach biotin (a vital coenzyme for carboxylase enzymes) to various molecules and surfaces through its amine group. This linker comprises a biotin moiety connected via an 11-unit polyethylene glycol (PEG) spacer to an amine group. The incorporation of PEG enhances the solubility and bioavailability of the conjugated molecules, reducing aggregation and steric hindrance, thereby facilitating a more effective interaction with biotin-binding proteins such as streptavidin or avidin.
