While, for example, the log2 ratios determined via microarray analysis of pooled screens from the constructs BIRC5-B (-0.948, p = 1.5e-3), BIRC5-C (-0.954, p = 3.2e-3) and HSPA8-A (-0.885, p = 2.0e-5) are almost identical, their viability at eight days post infection varies greatly (Figure 5A). Here, BIRC5 is linked to infection.
