Firefly luciferase circRNA-LNP is a lipid nanoparticle (LNP) containing Firefly luciferase circRNA, designed for applications such as RNA delivery, translation efficiency, and cell viability assays. Luciferase acts as a bioluminescent reporter gene commonly used in the study of gene regulation and function. Once introduced into cells, Firefly Luciferase circRNA expresses the firefly luciferase protein. It is typically used in promoter activity assays or dual-luciferase complementation experiments. Common types of luciferase include firefly luciferase and Renilla luciferase.
