| Description | CAG-ChIEF-tdTOMATO AAV (Serotype 2) is the serotype 2 AAV which expresses a hybrid of Channelrhodopsin-1/2 under CAG promoter with tdTOMATO tag. ChIEF is a hybrid of channelrhodopsin 1 and 2 with additional L170I mutation (ChR1 numbering) or at L131I (ChR2-numbering), leading to large currents in oocytes and HEK-cells and almost wild type like open state life time. ChIEF function as light-gated ion channels and very useful for many bioengineering and neuroscience applications such as photostimulation of neurons for probing of neural circuits. Using tdTOMATO tagged ChIEF, light-stimulated axons and synapses can be identified in intact brain tissue. This is useful to study the molecular events during the induction of synaptic plasticity. ChIEF has also been used to map long-range connections from one side of the brain to the other, and to map the spatial location of specific inputs on the dendritic tree of individual neurons. |

| 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. |
