Sulfo-Cy3-Tetrazine is water soluble cyanine dye containing tetrazine moiety for the coupling with trans-cyclooctenes, which is an inverse electron demand [4+2] cycloaddition that takes place between tetrazine and trans-cyclooctene or other strained olefin. This fluorophore is bright and very well visible with naked eye. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
Fluorescein isothiocyanate (FITC) is a yellow-orange molecule with an absorption maximum at 495nm. Upon excitation, it emits a yellow-green color with an emission maximum at 525nm. Fluorescein isothiocyanate is widely used to attach a fluorescent label to proteins via the amine group. The isothiocyanate group reacts with nucleophiles such as amino or thiol terminals. It has been used for the labeling of proteins including antibodies and lectins. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
