Only ratios from spots with intensity values 2 SD above the average slide background were used to calculate Pearson's correlations or Spearman's rank-correlations. The number of intensity values used in each correlation analysis is shown (n). All Pearson correlation values were statistically significant (p-value for rejecting Ho: r = 0 << 10-5).
