Synapsin-RFP AAV (Serotype 5)

Synapsin-RFP AAV (serotype 5) is a viral vector widely used in neuroscience research, especially for applications involving gene delivery to neurons. AAV is a small, non-pathogenic virus that can efficiently transfer genetic material into host cells. Of the various serotypes available, serotype 5 has been shown to efficiently transduce specific neural cell types. This specificity makes it particularly suitable for targeting neurons in both in vitro and in vivo studies. The choice of serotype affects the tropism of the viral vector, and serotype 5 is known for its ability to infect neurons more than other tissues, which is essential for achieving targeted and efficient gene expression in the central nervous system.

The synapsin promoter is a neuron-specific promoter that ensures that the transgene is expressed primarily in the neuronal population. Its specificity and strong activity in neurons make it ideal for studies aimed at manipulating neuronal function, tracing neuronal activity, or mapping neuronal circuits. By driving the expression of RFP, researchers can visually monitor the distribution and intensity of transgene expression. RFP is a well-known reporter protein that fluoresces red under specific lighting conditions and can be easily visualized using fluorescence microscopy.
