In Vitro Transcribed RNA-based Luciferase Reporter Assay to Study Translation Regulation in Poxvirus-infected Cells

Executive Industry Relevance

Translation regulation is a critical inflection point in antiviral drug discovery, where mechanistic de-risking and target validation depend on robust, quantitative assays. The in vitro transcribed RNA-based luciferase reporter assay enables precise interrogation of cis-element function and translation initiation mechanisms in poxvirus-infected systems. This capability supports predictive confidence for early-stage portfolio decisions and informs translational continuity across discovery and preclinical workflows.
