QbSure® R Value Predicts Assay Performance
Cells were stained with a PE Cy7 labeled antibody binding a low level of expression antigen (625 molecules/cell). Cells were run in three different cytometers, and in each one, the setup was optimized to maximize resolution.
R Value comparison using 8 Peak Beads
R Value: Resolution limit, or ‘R’, quantifies the number of dye molecules needed to resolve a dim population from the background. Low ‘R’ values indicate better performance.
