Fig. 1 — Associations of relative cytokine transcription levels (e.g. 2^−ΔC_T) with age. The value of 2^−ΔC_T, a standard method of expressing cytokine transcription levels, was calculated from the difference between the target and internal control C_T, as an n-fold difference relative to the calibrator fGAPDH. (Δ-individual cat cytokine value; •—• regression line from analysis).
