For amplification efficiency analysis, qPCR was performed in a 25 m l reaction volume containing the following: 1X SYBR Green PCR Master Mix (Applied Biosystems), 0.4 m M forward primer, 0.4 m M reverse primer, and template from the dilution series with the previously indicated concentrations. Three technical replicates were included for each sample. qPCR was performed in an ABI Prism 7000 Sequence Detection System (Applied Biosystems) using the following parameters: 50C for 2 min, 95C for 10 min, and 40 amplification cycles of 95C for 15 s, and 60C for 1 min. Dissociation curve analysis was performed at the end of the amplification cycles to examine for the occurrence of primer dimerization.
Standard curve analysis resulting from plotting observed cycle threshold (CT ) values vs. Log (concentration) followed by linear regression analysis was then used in conjunction with the equation Efficiency ¼ 10 (?1/Slope) ? 1 [36] tocalculate amplification efficiency for each primer pair. Primers with amplification efficiency of >0.87 are used in this study [37]. A full list of primers used in this study, their corresponding amplification efficiencies, and the database accessions for each gene can be found in Table 1.
