Biotin-PEG-Amine (MW 10000)

Biotin-PEG-Amine (MW 10000) (Biotin-PEG-NH2 (MW 10000) ) is a biotinylated PEG polymer that includes a free amine group (-NH2) . This amine group can form an amide bond by reacting with activated NHS esters. Compounds labeled with biotin can be linked to avidin or streptavidin for further purification or detection.
