    Product Description

    XFD514 acid is a non-reactive fluorescent probe. It displays excitation/emission maxima of 518/543 nm, respectively, and stable fluorescence at a pH range of 4 to 10. XFD514 acid can be used as a reference standard for XFD514-based conjugates and as a control in microscopy, immunocytochemistry (ICC), flow cytometry (FC), high-content screening (HCS), and live cell imaging applications. It can also be used in the synthesis of XFD514-based activated esters and 4-sulfo-2,3,5,6-tetrafluorophenyl (STP) and can be coupled with hydrazines, hydroxylamines, or amines to produce XFD514-based conjugates.
