Introduction to AAV-LC3 production service for Autophagy Flux Detection

Premade LC3 Autophagy Biosensors Products and user manual

LC3 Autophagy Biosensors User Manual

Autophagy is a self-degradative process in cell that is important for balancing sources of energy at critical times in development and in response to nutrient stress. For autophagy study, Genemedi supply autophagy biosensor, in which GFP and/or RFP tags are fused at the C-termini of the autophagosome marker LC3, allowing to detect the intensity of autophagy flux in real-time with more accuracy, clarity and intuitiveness. These biosensors provide an enhanced dissection of the maturation of the autophagosome to the autolysosome, which capitalizes on the pH difference between the acidic autolysosome and the neutral autophagosome. The acid-sensitive GFP will be degraded in autolysosome whereas the acid-insensitive RFP will not. Therefore, the change from autophagosome to autolysosome can be visualized by imaging the specific loss of the GFP fluorescence, leaving only red fluorescence.

Adeno associated virus (AAV)
Adeno associated virus (AAV) is one kind of human parvovirus. Recombinant AAV vectors can efficiently transfect various cell types, including dividing and quiescent cells, and induce persistent gene expression in vivo without integrating into host genome and causing any disease. These features make AAV an attractive candidate in the application of gene delivery for gene therapy and human disease model establishment. To date, AAV has been proved as the most excellent gene therapy vector. Over 204 clinical trials have been carried out using AAV vectors for gene delivery, and promising gene therapy outcomes have been achieved from clinical trials for a great number of diseases.

AAV-LC3 production service for Autophagy Flux Detection
Taking advantage of RFP-GFP-LC3 and GFP-LC3 labeling system, Genemedi has launched the production service of AAV-RFP-GFP-LC3 and AAV-GFP-LC3, which can be used to observe autophagy flux and monitor the intensity of autophagy flux in real-time in vivo or in vitro.


1. Real time and quantitative in vivo autophagy flux detection.

2. High resolution, more accuracy and sensitivity, than traditional approaches.

3. Safety. 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.

4. Low immunogenicity. AAV causes a very mild immune response, lending further support to its apparent lack of pathogenicity.

5. Broad range of host and specificity targeting. AAV has the ability to infect both dividing and quiescent cells, allowing genetic material to be delivered to a highly diverse range of cell types. More than 12 AAV serotypes and a variety of capsid engineered AAV vectors can be selected according to their tissue tropisms.

6. Stable physical properties. AAV is still alive at 60℃ and resistant to chloroform.

Applications and Figures

Quality control description

AAV capsid contains VR1 82kDa, VR2 72kDa and VR3 62kDa, which can be detected using the method of polyacrylamide gel electrophoresis (PAGE) followed by silver staining or Coomassie blue staining. Pure AAV should display only three major protein bands, such as shown in Fig 3.

Figure 3. PAGE for quality testing example of AAV by Genemedi. Only 3 protein bands can be seen in the purified AAV virus samples.
