AAV9-CAG-NLuc-2A-mCherry

AAV9-CAG-NLuc-2A-mCherry is a viral vector system that combines multiple advantages, making it particularly suitable for neuroscience research. This AAV serotype 9 vector exhibits excellent tropism for neuronal cells, enabling efficient transduction throughout the nervous system, including across the blood-brain barrier. The CAG hybrid promoter drives strong and sustained expression of dual reporter genes (NanoLuc luciferase and mCherry), while maintaining neuronal specificity. The inclusion of a 2A self-cleaving peptide ensures equimolar co-expression of both reporter genes without affecting the function of either protein. NanoLuc luciferase provides an extremely bright bioluminescent signal (100 times brighter than firefly luciferase), offering high sensitivity for quantitative analysis; while mCherry provides intuitive visual tracking and excellent photostability.

The AAV9-CAG-NLuc-2A-mCherry system has broad applications in neuroscience research and therapeutic development. It enables precise monitoring of neuronal activity patterns through bimodal imaging—combining sensitive bioluminescent detection and spatial fluorescent localization. Researchers utilize this vector construct to map neural circuits, track axonal transport, and study synaptic connections in vivo. The system is particularly valuable for longitudinal studies requiring repeated measurements, as the stability of NanoLuc allows for reliable signal detection over extended periods. In disease modeling, it aids in studying neurodegenerative processes, providing insights into disease mechanisms by correlating functional changes (via luciferase activity) and morphological changes (via mCherry fluorescence). This vector is an excellent platform for testing gene therapy approaches, with the reporter genes used to quantitatively assess transduction efficiency and transgene expression levels. Furthermore, the high brightness of the reporter genes makes high-throughput screening of neuroactive compounds in primary neuronal cultures possible.
