inquiryProduct Overview
Description
Herpes simplex virus (HSV) based on the H129 strain has been widely used as an anterograde tracer. The addition of fluorescent protein-modified HSV can not only effectively mark the connections between different brain regions, but also the connections between the surrounding and the center.
Thymidine nucleotide kinase (TK) is an important part of HSV replication after nerve cell infection. In the presence of TK, HSV can replicate and express target genes in cells, and its progeny viruses will be transported to the synapse, and then through the synapse to enter downstream neurons, thereby achieving multi-synaptic tracking. After deleting TK (deleting TK), HSV-ΔTK can infect neurons but cannot replicate. We know that only viruses that can replicate have the ability to cross synapses, so HSV-ΔTK cannot cross synapses. However, if we provide AAV virus as an assistant for expressing TK protein, HSV-ΔTK can achieve anterograde single synaptic tracking.
Application
●Multi-synaptic tracking from the center of the brain to the periphery, or from lower to higher brain regions.
●Track the connection between peripheral organs and the central nervous system
●Track the neural network in the disease or injury model.
● Changes in neural networks during neural development.

Q&As
What are the benefits of using tdTomato as the reporter in this vector?
Using tdTomato as the reporter in this vector offers several advantages. TdTomato provides bright and stable fluorescence, which is critical for long-term imaging and tracking. It also has a higher photostability and quantum yield compared to other fluorescent proteins, allowing for more precise visualization of neuronal structures. Additionally, its red fluorescence reduces overlap with commonly used green markers, facilitating multicolor experiments.
What precautions should be taken when handling the HSV-ΔTK-LSL-tdTomato (H361) vector in the laboratory?
When handling the HSV-ΔTK-LSL-tdTomato (H361) vector, it is essential to follow biosafety guidelines appropriate for BSL-2 agents. This includes using personal protective equipment, such as gloves and lab coats, and working in a biosafety cabinet to prevent contamination. Proper waste disposal and decontamination procedures should also be followed to ensure safety and compliance with laboratory standards.
What are the optimal conditions for injecting the HSV-ΔTK-LSL-tdTomato (H361) vector into the brain, and what factors should be considered?
The optimal conditions for injecting the HSV-ΔTK-LSL-tdTomato (H361) vector involve precise stereotaxic surgery to accurately target specific brain regions. Factors to consider include the volume and concentration of the viral solution, the speed of injection, and the choice of anesthesia to minimize tissue damage. Proper post-operative care and monitoring of the subjects are also critical to ensure successful expression and recovery.
