  1. The linear equation, efficiency and r-squared (RSq) values for the qPCR standard curve are shown. Plasmid copy numbers used as standards were determined by calculating the number of moles in each sample multiplied by Avogadro's number. A standard curve of Ct (dR) was used to calculate original copy number of mRNA transcripts in the diluted cDNA samples.
