AAV-GFAP-Fluc

AAV-GFAP-Fluc series viruses are ready to use AAV vectors carrying GFAP-Fluc expression cassette. The AAV-GFAP-Fluc vectors are available with 16 different serotypes, and there are over 1000 AAV serotypes/variants to be choose for custom AAV packaging.
The GFAP promoter refers to the regulatory sequence that controls the expression of the Glial Fibrillary Acidic Protein (GFAP) gene. GFAP is a key intermediate filament protein that is predominantly expressed in astrocytes, which are star-shaped glial cells in the central nervous system (CNS). The GFAP promoter is a glial-specific regulatory element that drives gene expression primarily in astrocytes within the central nervous system. It is a powerful tool in neuroscience research, gene therapy, and the development of transgenic models for studying astrocyte function, CNS development, and neurodegenerative diseases. Its specificity to astrocytes makes it invaluable for targeting gene expression in studies focused on glial cell biology, CNS health, and pathology.
Firefly luciferase (Fluc) catalyzes the oxidation of its substrate, luciferin, in the presence of ATP and oxygen, producing light in the yellow-green spectrum. This bioluminescent reaction is widely used in biological research for real-time imaging, monitoring gene expression, and tracking various cellular processes. AAV-Fluc is a powerful tool for researchers who need to perform sensitive, non-invasive imaging and monitoring of gene expression and other cellular processes. Its high sensitivity, broad dynamic range, and compatibility with various research models make it an essential component of many bioluminescence-based assays and in vivo studies.

Background

AAV viruses or AAV vectors, are a convenient solution for researchers who need to perform gene delivery experiments, such as gene therapy, gene editing, and gene regulation. The premade AAV viruses are available in various serotypes, promoters, and reporters/transgenes, allowing researchers to choose the most suitable vector for their specific research application. With over a thousand known AAV serotypes, customers have the tools to rapidly determine the vector specificity for various cell types. Additionally, the availability of multiple promoters paired with reporter genes allows for easy assessment and monitoring of gene expression levels and timing.

To ensure high-quality and pure products, various assays are used to assess the quality and purity of their AAV vectors:
· Gene specific qPCR Titer: Target the specific transgenes or common used elements, such as WPRE, CMV, PolyA, but not ITR.
· Full/Empty Particle Ratio: Ensure all the premade AAVs has >80% full particles by Mass Photometry.
· Endotoxin Testing: Ensure safety with endotoxin level <1U/1e13VG.
· SDS-PAGE Gel: Assess the purity of the AAV viruses is great than 95%.
· Infectivity Assay: Evaluate the efficiency of AAV viruses in transducing target cells if they have reporters.
