The viability of the DC vaccine was assessed by flow cytometry after propidium iodide (PI) staining, and is represented as 100−((PI+ of sample)−(PI+ of control)) (%).
The % represents the cell population in the DC gate (higher forward and side scattering (size and granularity increased)) based on the gating control with calibrating beads and PBMCs.
The % represents marker-positive cell populations based on the isotype control in flow cytometry.
