Excellent Predictive Value

Promega's homogeneous caspase assays are highly reproducible as measured by Z′ factors.

Z′ factor values are statistical indicators of the dynamic range and variability of assay results. Assays that produce Z′ factor values of 0.5 or greater are considered well suited for high throughput screening.
