**FAQs**

**Q: What is Z Prime used for in biochemistry?**

A: Z Prime is a statistical parameter used to assess the quality of high-throughput screening assays. It indicates the separation between the positive and negative controls.

**Q: Can Z Prime be negative?**

A: Yes, a negative Z Prime value suggests poor assay performance, indicating that the controls are not well-separated.

**Q: Is there a preferred Z Prime range?**

A: Generally, a Z Prime value above 0.5 is considered excellent, while below 0.5 may indicate the need for assay optimization.

**Q: Why is Z Prime important in drug discovery?**

A: Z Prime helps researchers evaluate the reliability and efficiency of screening assays, contributing to the identification of potential drug candidates.
