kit master mix (2X) ABI Prism amplification reaction mixture
containing 100 nM each of the AcKS10L and AcKS10R primers and
50 ng of template DNA. Control samples, without template DNA,
were also included in the runs. Reactions were prepared in duplicates
of 10 mL final volume, in MicroAmp optical 96-well reaction
plates sealed with optical adhesive covers (Applied
Biosystems, USA). Runs were performed in an Applied Biosystems
7500 Fast Real-Time PCR system (Applied Biosystems) using the
following amplification protocol: one cycle of 5 min at 95 C and
40 cycles of 15 s at 95 C and 1 min at 60 C. At the end of each
run, a dissociation protocol was performed to confirm the specificity
of the assay. Melting curves were programmed as 15 s at
95 C, 15 s at 60 C, 20 min slow ramp and 15 s at 95 C. The data
for the dissociation curve were captured during this slow ramp,
and the melting curves were visualized using ABI PRISM 7900
software. Quantification of the unknown DNA samples was carried
out by interpolating the samples' CT values from a standard
curve.
