Access endothelial cells efficiently in vitro - new AAV gene tools

Long lasting expression, any gene or shRNA, inducible TET optional

A new type of adeno-associated virus has been engineered and validated as efficient gene carrier into endothelial cells. The AAV5-derived endoAAV particles perform with outstanding results in vitro. FACS analysis shows that 63% of HCAEC cells can be transduced efficiently with this virus system. With this system the experimenter can benefit from the long-term expression that is typical 


FACS sorting analysis of HCAEC cells transduced with endothelial specific endoAAV.

This new endoAAV is now available to the research community.

Within the common size limits, the system can be used to package virtually ANY gene or shRNA coding sequence. Combine it with tissue specific promoters to further select for cell specificity or even use a TET-inducible promoter to time the expression for exact and convincing data. By combining target expression with selection markers the system enables selection of transduction positive clones and a high yield of pure transduction positive cells.

Optimize your CAR-T cell strategies  

With advanced lentivirus methods

Success in early clinical trials with small patient groups have made the CAR- (chimeric antigen receptor) approach to genetically reprogram T-cells a hopeful new technology to combat cancer.

While promising, several elements of the way that genetically modified T-cells are produced need to be refined to become marketable at a large scale.

SIRION Biotech is an expert in modifying and improving viral vector technologies to attune them to the specific requirements of modern R&D projects in the life sciences. SIRION's LV technology platform gives options to optimize cell transduction on every level:
  • LentiBOOST – a universal transduction enhancer that is especially potent in increasing T-cell transduction efficiencies.
  • LentiTHERAPY – Retargeting lentivirus by including customizable single-chain antibodies against a defined surface marker.
  • Custom LV cloning and production - All major expression systems are fully customizable, including options for custom promoters, inducible expression and knockdown systems. 
SIRION can support R&D of all sizes including projects aiming for clinical applications.

Feel free to contact us to discuss your particular ideas and needs.
