Figure 1From: Comparative transcriptomic analysis of Porphyromonas gingivalisbiofilm and planktonic cellsCorrelation between microarray and real-time PCR. Correlation between microarray and real-time-PCR gene expression ratios determined for biofilm versus planktonic cells. The log2-transformed microarray and real-time-PCR ratios were used to determine the Spearman Rank correlation coefficient (r = 0.86, p < 0.01).Back to article page
