Low‐Concentration Enhancement Effect: Enabling Sensitive Detection of EML4‐ALK Variants via Multiplex RT‐MIRA

Journal of Clinical Laboratory Analysis, EarlyView.
This study developed an optimized multiplex RT‐MIRA assay for the simultaneous detection of EML4‐ALK variants, achieving single‐copy sensitivity. Unexpectedly, during the development of the reaction system, we discovered a “low‐concentration enhancement effect,” where reducing primer or probe concentrations within a specific range markedly improved ...
