AAVBlast Transduction Enhancer: Innovating Molecular Transduction with AAV

The role of AAVBlast in transduction

The AAVBlast Transduction Enhancer plays a crucial role in enhancing transduction, a pivotal process in biomedical research. As a transduction enhancement agent, AAVBlast facilitates the entry of adeno-associated viral vectors into target cells, thereby increasing transduction efficiency.

AAVBlast is specifically designed to improve the transduction of adeno-associated viral vectors (AAV). These vectors are commonly used in gene therapy and biomedical research due to their ability to deliver genes into various types of cells.

By enhancing transduction efficiency, AAVBlast enables more effective gene delivery, leading to more precise research results and more efficient gene therapies. Additionally, the use of AAVBlast can reduce the amount of viral vector needed to achieve effective results, thereby lowering costs and risks associated with viral vector use.

The role of AAVBlast in transduction is to enhance the efficiency and precision of gene delivery, with significant implications for biomedical research and gene therapy.

The benefits of using AAVBlast in research

The AAVBlast is a transduction enhancer that offers several advantages for research. Here are some key benefits of using AAVBlast in research:

• Improved Infection Efficiency: AAVBlast enhances the efficiency of AAV infection, particularly for cells that are challenging to transduce.
• Non-Toxicity: AAVBlast is non-toxic, making it compatible with in vivo experiments.
• Increased Efficiency: The use of AAVBlast may allow achieving the same transduction results with a lower viral titer, potentially saving time and resources.

These advantages make AAVBlast a valuable tool for gene therapy research.

Applications and protocol of AAVBlast transduction enhancer

AAVBlast applications 

The AAVBlast transduction enhancer is recommended for improving AAV transduction across a wide range of cell types, from CD34+ hematopoietic stem cells to primary cells or cell lines such as HT1080 or SH-SY5Y. It is perfect for enhancing AAV transduction in CD34+ hematopoietic stem cells, T lymphocytes, as well as any other cell.

AAVBlast is ideal for enhancing research and development, preclinical, and clinical transduction protocols for ex vivo gene therapies and CAR-T therapies. Here are some specific applications:

1. Ex Vivo Gene Therapies: AAVBlast can be used to improve the efficiency of AAV vector transduction in CD34+ hematopoietic stem cells. This can enable better expression of the gene of interest, which is crucial for the success of gene therapies.
2. CAR-T Therapies: AAVBlast can also be used to enhance transduction of T lymphocytes with AAV vectors carrying chimeric antigen receptors (CAR). This can increase the efficiency of CAR-T therapies by boosting the number of T cells expressing the CAR.
3. Stem Cell Research: AAVBlast can be used to enhance the transduction of stem cells with AAV vectors. This can be beneficial for stem cell research, including the study of stem cell differentiation and disease modeling.

4. Neurodegenerative Disease Research: AAVBlast can be used to improve transduction of neurons with AAV vectors. This is particularly useful for neurodegenerative disease research, where gene expression in neurons is often necessary 

In summary, AAVBlast is a valuable tool for improving the efficiency of AAV transduction in a variety of research and clinical contexts. Its versatility and effectiveness make it a valuable addition to any laboratory working with AAV vectors.

AAVBlast protocol

• Cells preparation: 

Cell culture prior to transduction: the day before transduction prepare the cells according to the table below. Cells should be 80-90 % confluent at the time of transduction (see the suggested cell number in the Table 1).

IMPORTANT NOTE

For hard-to-transduce or non-permissive cells, and depending on serotype, prepare the cells the day of transduction and refer to reverse-transduction procedure below.

• Standard protocol 

Use the quick protocol above to find the ideal conditions for AAVBlast in 24-well plate. If the AAV transduction/infection conditions are unknown, starting with MOI ranging from 1000 gc (genome copies) to 30000 gc per cell using an AAV encoding for a fluorescent protein.

NOTE: We suggest using 0.5, 1 µL and 2 µL of AAVBlast per condition.

• Reverse transduction-protocol

Reverse transduction, alternatively referred to as substrate-mediated gene delivery, involves the initial coating of viral vectors onto a surface.

It may be a good alternative to classic transduction depending on cell type or virus serotype.

1) Follow steps 2 to 5 of the quick protocol

2) Add AAV/AAVBlast mixes to the plate

3) Store the plates at 4°C overnight

4) On the day of transduction, carefully aspirate the virus solution from the plate

5) Add the cells to the plate in their complete culture medium

6) Optionally, cells can be added in medium w/o supplement for 2H before serum supplementation
