Reagent lot changes account for over half of experimental variance, yet labs rarely audit them.
Standardized lot comparisons, not just pass-fail stamps, catch the drift that kills reproducibility.
Most CFPS suppliers keep formulations secret, blocking troubleshooting.
Ring studies prove a protocol works across labs, not just in one.
