5-FITC-DBCO

FITC is a kind of green fluorescein derivative with high absorption rate, excellent fluorescence quantum yield and good water solubility.Its isothiocyanate group can react with amino terminal or primary amine of protein to realize protein labeling including antibody and lectin.Dibenzocyclooctyne (dbco) was used in the azido alkyne cycloaddition (spaac) reaction without copper ion catalysis.The kinetic constant of the second order reaction was 1. Dbco series products include dbco acid,dbco amine,dbco peg COOH,dbco peg amine,as well as dbco labeled biotin,fluorescent dyes and biochemical small molecules.
