Principal component analysis (PCA) plot showing transcriptome differences between expression microarray data of GBS strain NEM316 strain incubated in human blood at 37°C and 40°C.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
Samples were analyzed at time 0, and after 30 min and 90 min of incubation. The PCA plot captures the variance in a dataset in terms of principal components and displays the most significant of these on the x, y, and z axes. The percentages of the total variation that are accounted for by the 1st, 2nd, and 3rd principal components are shown on the x-, y- and z-axes labels. Plots are colored by temperature of incubation and shaped by time point. Elipses circled plot each time point.
