Embodiment Construction
[0039] refer to figure 1 , the embodiment of the present application provides a detection method for Staphylococcus aureus, comprising the following steps:
[0040] Step S1, combining the first probe, the second probe and single-stranded DNA (ssDNA) into a double fluorescently labeled probe (TFP) with two carboxyfluorescein (FAM);
[0041] The DNA sequence of the first probe is 5'-FAM-TCTAGA-3';
[0042] The DNA sequence of the second probe is 5'-TCTAGA-FAM-3';
[0043] The sequence of the single-stranded DNA is 5'-TCTAGAAGTTATCCCAGTCTTATAGGTAGGTTCATGA-3';
[0044] Said forming the first probe, the second probe and the single-stranded DNA into a double fluorescently labeled probe with two carboxyfluoresceins includes:
[0045] Denature 50 nM of the first probe, second probe and single-stranded DNA in a water bath at 95°C for 5 minutes, and then ice-bath for 10 minutes; Mix and incubate at room temperature for 30 min to form a double fluorescently labeled probe with two car...
