Virus Tracer Products

Neural circuit mapping relies heavily on tracers to delineate neuronal projections and connectivity. While traditional chemical tracers like horseradish peroxidase and dextran amine were foundational, their limitations—including non-specific labeling, inconsistent transsynaptic efficiency, and significant signal decay—restrict their utility. Viral tracers, leveraging genetic engineering, overcome these challenges, offering superior cell-type specificity, reduced toxicity, and robust transsynaptic transmission.

Viral tracers are indispensable tools across diverse neuroscience domains, from pain modulation and anxiety behavior studies to intricate neural circuit analysis. We offer a comprehensive suite of viral tracer products, encompassing anterograde, retrograde, and transsynaptic tracing capabilities.

Virus Type

Viral tracers are broadly classified by their synaptic transmission capability: transsynaptic and non-transsynaptic. Transsynaptic viruses (e.g., PRV, RV, CAV-2) propagate across synapses, enabling the mapping of interconnected neural networks. Conversely, non-transsynaptic viruses restrict infection to local neurons. Furthermore, tracers are categorized by their transport direction: anterograde and retrograde. Anterograde tracers (e.g., AAV, HSV) move along axons, tracing downstream projections, while retrograde tracers (e.g., retrograde AAV) travel along dendrites, revealing upstream connections.

Advantages of Viral Tracers

Our viral tracers offer distinct advantages for precise neural circuit mapping:

Targeted Labeling: Gene editing enables precise labeling of specific neuronal populations, overcoming the limitations of traditional tracers.
Synaptic Pathway Tracing: Modified transsynaptic viruses (e.g., PRV, RV) facilitate the mapping of intricate neural connections.
Enhanced Safety: Virulence gene deletion, such as PRV envelope protein removal, significantly reduces toxicity, ensuring suitability for prolonged studies.
Advanced Circuit Analysis: Innovative tracers, like three-level loop tracing, enable comprehensive multi-level neural circuit investigations.
