Viral vector systems to improve transduction

SIRION Biotech offers custom engineering of viral vectors to improve transduction and performance of in-vitro cell modelling, in-vivo gene modification and therapeutic research and development (R&D).

The company’s virus-based technologies are used worldwide in academia and industry. SIRION’s strong focus on transduction technologies enables it to offer customisation services for all three major virus types, lentivirus (LV), adenovirus (AV) and adeno-associated virus (AAV).

Viral vector engineering and manufacture

SIRION engineers and manufactures replication-deficient LV, AAV and AV vectors. The platform offers many add-on options such as inducible expression systems, tissue-specific promoters and specialised transduction boosters for tight expression control.

Custom adeno-associated virus service

SIRION can manufacture a range of AAV serotypes and can engineer these with tissue-specific promotors to increase expression precision of nearly any gene of interest.

SIRION Biotech enables full gene expression control in mammalian cells.
Viral vectors are an ideal tool to shuttle genetic material into mammalian cells.
SIRION Biotech provides custom engineering and production services for lentivirus, adenovirus, and adeno-associated virus (AAV).

Fast protein liquid chromatography (FPLC) grade AAV manufacture techniques provide high-purity products for R&D in less than eight weeks. The sophisticated platform allows the integration of desired expression constructs within the vector’s cloning capacity. Batch sizes range from 5×1011 genetic copies (GC) for small explorative experiments all the way to 5×1014 GC to satisfy complete experimental cohorts.

Additional in-house features of the SIRION AAV technology platform include capsid modifications to target cell-specific transduction. All projects are personally planned with highly trained project managers to ensure resulting vector designs and function fit the client’s intended application.

Custom lentivirus service

SIRION BIOTECH`s custom LV vector service enables the manufacture of constitutive and inducible gene vectors in less than four weeks.

SIRION’s multicistronic vector designs enable customers to create highly homogeneous, stable cell pools, and avoid time-consuming clone selection after transduction.

With the all-in-one inducible vector system, SIRION enables working with difficult cytotoxic genes and knockdown strategies. The manufacture of scales up to 1×109 TU is possible.

Custom adenovirus service

SIRION`s patented BAC technology enables AV construction in less than five weeks.

The system complies with standard safety criteria by using replication-deficient E1/E3 deleted serotype Ad5 as base vector. Desired genes or knockdown expression construct is possible, within a 7.5kb limit.

Transduction enhancers for difficult cell types

SIRION’s in-house developed transduction boosters enable working with difficult-to-transduce cell types such as hematopoietic cells.

The LentiBOOST™ reagent is currently used in several clinical trials to improve genetic modification of hematopoietic stem cells or T-cells for gene-therapy and chimeric antigen receptor T-cell (CAR-T) cell projects.

Developing novel AAV for gene therapy – NextGen AAV

AAVs are heavily utilised in modern gene therapy trials. While standard AAV applications are suitable for pre-clinical target validation and proof-of-principle experiments, they often fall short during the big step into clinical application.

SIRION´s AAV optimisation platform enables you to address AAV limitations before you take that crucial step. All elements of your AAV strategy are considered and optimised with your project’s specific goals in mind.

Products & services

  • NextGenAAV

    SIRION Biotech offers full customisation services for gene therapy research and development (R&D). The company optimises adeno-associated virus (AAV) tissue specificity and immunogenic profiles.

  • Adenovirus

    SIRION Biotech’s engineered adenovirus vectors are used for transient and quantitative gene expression or knockdown.

  • Lentivirus

    SIRION Biotech provides engineered Lentivirus vectors for gene expression and knockdown. Lentivirus vectors are the method of choice whenever a fast, efficient and cost-effective generation of stable cell models is required.

  • Adeno-associated virus (AAV)

    SIRION Biotech provides engineered adeno-associated virus (AAV) vectors for in-vivo gene expression and knockdown experiments, which help uncover the phenotypic impact of a genetic modification on the level of the living organism. AAVs are ideal for this kind of application.

  • LentiBOOST™

    Maximise your virus uptake with transduction enhancers. Restricted uptake of virus particles often lowers the success of gene or short hairpin ribonucleic acid (shRNA) expression and requires the application of higher viral titers.
