Creative Biogene ensures high-quality AAV particles by optimizing and standardizing production protocols and performing stringent quality control (QC). The specific QC experiments performed vary between AAV particle lots.
Endotoxin Endotoxins, primarily derived from Gram-negative bacteria, can trigger adverse immune responses. Endotoxin contamination is a significant concern in the production of AAV, especially for applications in animal studies and gene therapy. Effective endotoxin quality control is essential in the development and manufacturing of AAV particles. Creative Biogene utilizes rigorous endotoxin detection methods to monitor the endotoxin level in our produced AAV particles to ensure regulatory compliance.
Purity AAV purity is critical for ensuring the safety and efficacy of AAV-based applications.AAV capsids are composed of three main protein components, known as viral proteins: VP1, VP2, and VP3. These proteins play a critical role in the structure and functionality of the AAV capsid. Monitoring the VP1, VP2, and VP3 content in AAV preparations is essential for quality control in AAV production. Our AAV particles are tested for showing three clear bands of VP1, VP2 VP3 by SDS-PAGE.
Sterility The AAV virus samples are inoculated into the cell culture medium for about 5 days to detect bacterial and fungal growth.
Transducibility Upon requirement, Creative Biogene can perform in vitro or in vivo transduction assays to evaluate the ability of AAV to deliver genetic material into target cells or tissues, and assess gene expression and functional activities.
Empty vs. Full Capsids Based-on our proprietary AAV production and purification technology, Creative Biogene can always offer AAV particles with high ratio of full capsids. If required, we can also assess the ratio for a specifc lot of AAV particles by transmission electron microscopy (TEM) or other methods.

AAV9-hSyn-ChR2(H134R)-YFP is a cutting-edge optogenetic tool that combines the advantages of adeno-associated virus serotype 9 (AAV9) with neuron-specific targeting capabilities. This viral vector utilizes the human synapsin (hSyn) promoter to drive the highly specific expression of the channelrhodopsin-2 (ChR2) light-gated channel in neurons, enabling precise optical control of targeted neurons. The engineered ChR2(H134R) variant exhibits higher light sensitivity and enhanced channel conductance compared to wild-type ChR2, while maintaining fast kinetics suitable for precise temporal control. Fusion with enhanced yellow fluorescent protein (EYFP) allows for easy visualization of transduced neurons via fluorescence microscopy. The AAV9 serotype was chosen for its superior central nervous system tropism, efficient neuronal transduction capabilities, and ability to cross the blood-brain barrier in some applications, resulting in broader distribution compared to other serotypes.

This viral vector is a powerful tool for neuroscience research, enabling optogenetic manipulation of neuronal activity in various experimental paradigms. It is particularly valuable for circuit mapping studies, which require precise excitation of specific neuronal populations to investigate synaptic connections and information flow within neural networks. Researchers use this construct to establish causal relationships between specific neuronal activity patterns and behavioral outputs in awake animals, facilitating studies of learning, memory, decision-making processes, and neurological disorders. The hSyn promoter restriction ensures that optogenetic stimulation is confined to neurons, making it ideal for cell-type-specific studies without the need for an additional Cre-dependent system. This construct has been successfully applied in both in vivo (stereotaxic injection) and in vitro (primary neuronal cultures, brain slices) experiments.
