Figure 1. Microarray presence or absence calls in three human trabecular meshwork cell cultures

Untreated and dexamethasone-treated human TM cell cultures were analyzed by Affymetrix U133A microarrays and the average number of probes in each category recorded for each individual cell culture. Probes were scored; absent:absent, absent:present, present:absent, or present:present (untreated:dexamethasone-treated), using MAS5.1 software as described in the Methods. The fraction of the number of probes in each category compared to the total number of probes is shown as bars for each cell culture. A composite average comparing all untreated to all dexamethasone-treated cell cultures is shown on the right.
