Biotin-PEG6-Silane（Cat No.:I044631）is a multifunctional reagent combining a biotin moiety, a six-unit polyethylene glycol (PEG6) spacer, and a silane group for surface immobilization. The biotin enables strong, specific binding to streptavidin or avidin proteins, facilitating detection, capture, or labeling. The PEG6 linker enhances water solubility, reduces nonspecific binding, and provides spatial flexibility. The silane group covalently attaches to hydroxylated surfaces such as glass, silica, or metal oxides via silanization. Biotin-PEG6-Silane is ideal for surface functionalization in biosensor development, microarrays, biomaterials engineering, and biointerface design.
