  1. SD: standard deviation of the ΔCt values
  2. Values marked with different superscript characters indicate groups (for the same target-mix combination) that are significantly different according to Tukeys HSD test (P < 0.05); xa is different from yb, z abis not different from either.
  3. ND: not detected or negative ΔCt.
  4. The temperature shows the optimal temperature from which the data were analysed.
