芃硕生物(Ponsure)的生物素-PEG-氨基(BIOTIN-PEG-NH2)是常卖产品之一,氨基(-NH2)可以很容易的和羧基形成稳定的酰胺键,也可以和活性酯(-NHS)在PH7-8.5形成酰胺键。 生物素(Biotin):Biotin functionalized polyethylene glycol (PEG-Biotin) is an avidin or streptavidin binding PEG derivative that is used to biotinylate biomolecules or other material surfaces. Biotin can be easily detected by biotin/streptavidin binding assay and is widely used for molecule target detection.
