Lipophilic sulfophenylcarbocyanine dyes: Synthesis of a new class of fluorescent cell membrane probes
摘要:
Two lipophilic sulfophenylcarbocyanine dyes, 3 and 4, were synthesized as a new class of fluorescent cell membrane probes. Compared with other commonly used membrane probes, the new dyes have improved fluorescent quantum yield, retention in cell membranes and are easier to use in staining cells.

An easy operable method of detecting phosphatase which comprises a step for the production of a dye to obtain an azo dye by the reaction of phosphatase in a tissue or cell or on chromosome with a 2'-naphthol AS phosphate, e.g. 3-hydroxy- N-2-biphenyl-2-naphthalenecarboxamide phosphate ester, followed by the reaction between the 2'-naphthol AS phosphate with a diazonium salt; an excitation step for the irradiation of excited light to the azo dye; and a detection step for the detection of fluorescence which is emitted upon irradiation of the excited light. The fluorescence is intense and lasts for a long time.
