Figure 4From: Phenotypic, genomic, and transcriptional characterization of Streptococcus pneumoniae interacting with human pharyngeal cellsValidation of microarray data by qRT-PCR. mRNA levels of 21 genes obtained by microarray (y-axis) and qRT-PCR (x-axis) are plotted. A, TIGR4 adherent bacteria; B, TIGR4 non-adherent bacteria; C, G54 adherent bacteria; D, G54 non-adherent bacteria. Graphs show a positive correlation between microarray log2 ratios and qRT-PCR ΔCt.Back to article page
