<正>A rapid and sensitive tluorimetric method for determination of spermine in tumor cell was described.The method was performed by purified,recombinant PAOh1/SMO protein coupled with horseradish peroxidase reaction,in which non-fluorogenic substrate HPPA can liberate fluorescence after accepting electron.The Ex was 340nm and the Em was 430nm,respectively.The
