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, specifically, 3-hydroxy- N-2'-biphenyl-2-naphthalenecarboxamide phosphate ester, followed by the reaction between the dephosphorylated 2'-naphthol AS compound 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.
一种易于操作的检测磷酸酶的方法,包括以下步骤:通过组织或细胞或染色体中的磷酸酶与2'-naphthol AS磷酸盐(具体为3-羟基-N-2'-联苯基-2-萘酰胺磷酸酯)反应以获得偶氮染料的制备步骤,随后将去磷酸化的2'-naphthol AS化合物与重氮盐反应;通过激发光照射偶氮染料的激发步骤;以及通过检测发射激发光照射后发出的荧光的检测步骤。荧光强烈且持续时间长。
