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.

EF1a-eNpHR 3.0-EYFP AAV (serotype 9) is an adeno-associated virus (AAV) vector specifically designed for use in the field of optogenetics. Optogenetics is a technique that combines genetics and optical methods to control and monitor the activity of single neurons in living tissue. Serotype 9 of this AAV is noted for its broad tropism and efficient transduction in a variety of tissues, including the central nervous system, making it a popular choice for neuroscience research. The EF1a promoter is a potent, constitutively active promoter derived from the human elongation factor-1α gene. It is able to promote stable expression of transgenes in a variety of cell types. In this construct, the EF1a promoter drives the expression of eNpHR 3.0-EYFP. eNpHR 3.0 (enhanced halorhodopsin) is a light-activated ion pump used to hyperpolarize neurons, thereby inhibiting their activity. This version of halorhodopsin has been genetically engineered to improve membrane trafficking and increase the efficiency of neuronal silencing. EYFP (Enhanced Yellow Fluorescent Protein) is fused to eNpHR 3.0 as a fluorescent marker. This fusion allows researchers to visualize and confirm the expression of the construct within the target cells. The bright fluorescence of EYFP makes it an excellent tool to track the efficiency of viral delivery and the spatial distribution of transduced cells within tissues.
