EF1a-eArch 3.0-EYFP AAV (Serotype 9)

EF1a-eArch 3.0-EYFP AAV (serotype 9) is an advanced viral vector designed for precise gene delivery. The vector is specifically designed to express the eArch 3.0-EYFP fusion protein driven by the EF1a promoter, ensuring its stable and sustained expression in target cells. The EF1a promoter is highly regarded for its ability to efficiently express in a variety of cell types, making this vector highly versatile for research applications. Serotype 9 AAV vectors were chosen for their excellent blood-brain barrier penetration and broad tropism in different cell types and tissues, especially in the central nervous system. This serotype is known for its efficient neuronal transduction capabilities, making it ideal for neurological research that requires a robust gene delivery system.

The eArch 3.0 component is a light-driven outward proton pump that represents an enhanced version of the original Arch (archaeobotrysin). Upon illumination, eArch 3.0 is able to effectively hyperpolarize neurons, inhibiting their activity. This property is crucial for neuroscientists who aim to temporarily silence specific neuronal populations to reveal their functional roles in complex neural networks. The fusion of eArch 3.0 with EYFP not only facilitates tracking and visualization of protein expression within living cells, but also ensures precise monitoring of their localization. EYFP has bright fluorescence and is an important tool for verifying successful delivery and expression of AAV viral particles and for conducting high-resolution imaging studies.
