(C) Percentage expression of amplicons of interest (A or B) relative to total amplified products, per reaction, are presented as a mean for each respective group (C, E, and NE). Error bars represent ±1 standard deviation. p values were calculated by one-way analysis of variance (ANOVA); ∗∗∗∗p < 0.0001, ∗∗∗p < 0.001, ns, non-significant.
