Figure 4. Example of OpenCyto automated gates on the perforin channel for CD8+ T-cells for six randomly selected samples from the HVTN 080 ICS data set.

Figure 4

The perforin marker exhibits staining variability as evidenced by the varying width and position of the negative peak and was not gated by the manual template-gating approach. Despite this variability, OpenCyto data-driven automated gating is able to identify a reasonable threshold for perforin positive cells.
