Pyrene PEG DBCO

Pyrene PEG DBCO:

Pyrene PEG DBCO is one of Nanocs’ reactive fluorescent pyrene dyes that can go Click Chemistry reaction. Pyrene is a unique fluorescent dye that has exceptionally long excite-state lifetimes (>100 nanoseconds). The long excited-state life time of this dye makes it useful for time-resolved fluorescent immonoassays, probing oxygen in cells and lipid vesicles. DBCO is a strain-promoted cyclooctyne that can react with azide group spontaneously without need any catalyst. DBCO is a commonly used Click Chemistry reagent because of its high reactivity and ease to use. Reaction between DBCO and azide group allows easy and quick conjugation of pyrene to proteins, antibodies nucleic acids or particles. PEG linker between Pyrene and DBCO group offers better water solubility, less steric hindrance and enhanced stability. Compared to other common fluorescent dyes, Nanocs’ reactive fluorescent PEG dyes are brighter, more stable and easier to use. All our reactive fluorescent PEG dyes can be used directly in aqueous buffer without need adding any organic solvents.
