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.

Q & A

Customer Reviews

Adeno-associated virus (AAV) is a small, non-enveloped virus that is widely used as a vector for gene therapy due to its ability to infect both dividing and non-dividing cells and elicit a mild immune response. In the absence of a helper adenovirus, AAV can integrate into the host genome without causing any significant pathogenic effects. There are several serotypes of AAV, each with different tissue tropisms, allowing targeted delivery to a variety of tissues such as liver, muscle, brain, and retina. This versatility expands the potential applications of AAV in treating a variety of genetic diseases. The use of AAV2 vectors in gene therapy has shown promise in several areas. For example, AAV2 has been used to treat retinal diseases such as Leber's congenital amaurosis (LCA), showing the potential to restore vision in patients. In addition, AAV2-based vectors are being explored for the treatment of diseases such as muscular dystrophy, hemophilia, and neurodegenerative diseases. AAV-SIG particles contain a specially modified capsid derived from AAV2, including the insertion of the peptide sequence SIGYPLP at position I587. The peptide SIGYPLP can enhance the virus's affinity for endothelial cells. This modification is crucial for the virus's ability to target and infect specific cells, improving the precision and effectiveness of gene delivery.
Customer Q&As
Is Adeno Associated Virus safe?

A: The wild type Adeno Associated Virus (AAV) has not currently been known to cause disease, and further security of recombinant AAV is ensured after removal of most AAV genome elements.

How do you increase AAV yield?

A: Currently, AAV yield is increasing through the use of various cell lines, assembly systems, transfection types, and downstream stage optimization.
