TCO PEG Fluorescein, TCO-PEG-FITC
TCO PEG Fluorescein, TCO-PEG-FITC, TCO-PEG-FAM, MW 5000
TCO PEG Fluorescein, also termed as TCO PEG FITC is a fluorescentPEG TCO derivative that gives strong green fluorescence. TCO (transcyclooctene) group reacts with tetrazine group fast and efficiently while fluorescein is a strong green fluorescent molecule that has excitation/emission wavelength around 495/515 nm. Fluorescein can be easily detected by fluorescent instruments at FITC channel. The reaction of TCO and tetrazine is a bioorthogaonal reaction that enables the conjugation of two molecules in aqueous solution fast and efficiently. PEG TCO derivatives have excellent water solubility, possess fast kinetics and stability in aqueous buffer. They are one of the best pegylation reagents to modify proteins, peptides, antibodies, biopolymers and particles via copper free Click Chemistry reaction.
