Figure 2From: Transcriptional and apoptotic responses of THP-1 cells to challenge with toxigenic, and non-toxigenic Bacillus anthracisA) Principle component analysis of microarrays run in this study confirms groupings of similar treatments, time points, and experimental replicates. Each color corresponds to the same experimental treatment, while each point represents a separate chip. Axes labeled PC1, PC2, and PC3 and represent Principle Component 1, Principle Component 2, and Principle Component 3, respectively. B) Variance of principle components evaluated.Back to article page
