    5(6)-Carboxyfluorescein diacetate, NHS ester

    $149.61

    Cell cycle, cell viability probe useful for cell labeling, especially in flow cytometry. Learn More
  3. 4-Trifluoromethylumbelliferone (TFMU)

    4-Trifluoromethylumbelliferone (TFMU)

    $37.37

    This slightly longer wavelength analog of 4-methylcoumarin (4-MU) has a pKa that more closely matches physiological pH values. Learn More
  4. Fluorescein diacetate (FDA)

    Fluorescein diacetate (FDA)

    $59.85

    FDA is one of the most widely-used green fluorogenic substrates for esterase activity. FDA is also a common viability stain for plant cells, protoplasts and tissues. Learn More
