Biotin PEG Linkers: Essential Tools for Accurate Purification and Detection
Biotin PEG linkers are invaluable in molecular biology and biochemistry for non-radioactive purification, detection, immobilization, labeling, and targeting. Combining the high affinity of biotin (vitamin H) with the solubility benefits of polyethylene glycol (PEG), these linkers form highly stable complexes with avidin and streptavidin, even under extreme conditions like varying pH, temperature, and organic solvents.
