AAV-hSyn-iCre

AAV-hSyn-iCre series viruses are ready to use AAV vectors carrying hSyn-iCre expression cassette. The AAV-hSyn-iCre vectors are available with 16 different serotypes, and there are over 1000 AAV serotypes/variants to be choose for custom AAV packaging.
The hSyn promoter, also known as the human Synapsin 1 promoter, is a regulatory sequence used to drive gene expression specifically in neurons. Synapsin 1 is a neuron-specific phosphoprotein that plays a crucial role in the regulation of neurotransmitter release at synapses. The hSyn promoter is a neuron-specific regulatory element that drives strong and selective gene expression in neurons. It is widely used in neuroscience research, gene therapy, the development of transgenic models, and optogenetic studies. Its specificity to neurons makes it invaluable for targeting gene expression in the nervous system, facilitating research into neuronal function, connectivity, and neurological disorders.
iCre is a codon-optimized variant of Cre recombinase, designed to enhance its expression and efficiency in mammalian cells. Like the standard Cre recombinase, iCre recognizes loxP sites and catalyzes site-specific recombination between them, which can result in the deletion, inversion, or translocation of the DNA sequence flanked by these sites. AAV-iCre offers an improved and more efficient approach to conditional gene manipulation, providing researchers with a powerful tool for studying gene function, lineage tracing, and gene editing.

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.
