What is Gene Therapy?

Gene therapy is transforming the treatment of rare and complex diseases by addressing their underlying genetic causes. Since the early 2000s, it has emerged as a promising approach for treating conditions such as leukemia, Parkinson's disease, and certain cancers by replacing defective genes or silencing disease-causing ones.

As gene therapy advances, innovative technologies are streamlining the development of these therapies. Viral vector manufacturing is one of the most common approaches, using adeno-associated viruses (AAVs) and lentiviruses (LVs) to deliver therapeutic genes into target cells and enable effective gene transfer.

Viral Vector Manufacturing

1. Cell Line Transfection for AAV/LV Production

Producing AAVs or LVs carrying the desired transgene requires the development of stable producer cell lines from single cells, followed by the selection of the highest-performing clones for large-scale manufacturing.

 

2. Single-cell cloning 

The UP.SIGHT combines dual imaging for confident monoclonality verification with whole-plate colony tracking, enabling researchers to efficiently identify and select high-producing clones.

3. Selection of High-Performing Cell Lines and Biobanking

After sorting cells with the UP.SIGHT, final selections of clones are targeted for long-term viral vector manufacturing.

High Clonality Probability for Viral Vector Manufacturing

High-confidence monoclonality is critical for selecting stable producer cell lines that consistently generate high-quality viral vectors. The UP.SIGHT platform supports this process with precise single-cell isolation, dual imaging for clonality assurance, and whole-plate colony tracking, helping researchers efficiently identify and document high-performing clones for downstream manufacturing and biobanking.

Cell culture and clonal expansion

Efficient clonal expansion is critical for developing high-yield producer cell lines for viral vector manufacturing. CYTENA's single-cell dispensing and imaging technologies support the isolation, monitoring, and expansion of suspension-adapted cells, helping researchers establish stable, high-performing clones ready for scale-up and manufacturing.

Single-Cell Cloning and Clonal Cell Culture

Single-cell cloning is the foundation of developing stable, high-performing producer cell lines for viral vector manufacturing. CYTENA's single-cell dispensing technology enables reliable isolation of individual cells, while its imaging technology provides traceability of clonal growth, helping researchers generate consistent, high-quality cell lines for gene therapy development.
