Utilizing state-of-the-art facilities and cutting-edge technologies, we ensure the production of replication-incompetent lentiviruses and other viral vectors that meet stringent regulatory and quality standards. Our team of experienced scientists provides tailored services, from the initial design phase through to the final product, guaranteeing robust titers and purity levels that enhance the efficiency of your CAR-T research. With a commitment to transparency and collaboration, we facilitate every step of the process, enabling clients to focus on their innovative work while we handle the complexities of virus manufacturing.

Manufacturing Process

Our manufacturing process of RG virus for CAR T-cell therapy involves several meticulously controlled steps to ensure the production of high-quality viral vectors, essential for effective gene transfer. Initially, the process begins with the selection of appropriate plasmids that encode the desired CAR and any necessary viral packaging components. The plasmids are then transfected into a suitable producer cell line, often HEK293 cells, using calcium phosphate or lipid-based transfection methods. Following transfection, the cells are cultured in bioreactors under optimized conditions to facilitate viral assembly and release. Once sufficient viral titers are achieved, the supernatant is harvested and subjected to purification processes, including filtration and chromatography, to remove impurities and isolate the RG virus. Subsequently, the purified virus is characterized through techniques such as titer determination, quality control assays, and sequencing to ensure the absence of contamination and verify the integrity of the viral genome. Finally, the RG virus is formulated for storage and distribution, ensuring compliance with regulatory standards for research use.

Research Grade vs. Clinical Grade (CG)

• RG viruses are produced for research purposes, allowing for experiments and preclinical trials.
• They are distinct from CG vectors, which are produced under Good Manufacturing Practice (GMP) conditions for human applications.
• RG vectors may not fulfill the rigorous safety and quality standards mandated for clinical use.

Key Advantages

• Integrated Platform Expertise: We offer manufacturing services for lentivirus, retrovirus, and AAV vectors, providing a truly platform-agnostic approach to vector selection based on the specific needs of your CAR-T project.
• Scalability Blueprint: Our RG process is intentionally designed as a blueprint for eventual GMP manufacturing. This eliminates the need for a costly and time-consuming process re-development later on.
• Best-in-Class QC Panel: Our quality control includes not only standard titer and sterility checks but also sensitive assays for residual host cell DNA and protein, ensuring the highest purity for your precious T-cell modifications.
• Published Data: Our proprietary cell lines and optimization methods have consistently delivered high-titer vectors, supporting numerous client programs that have successfully progressed into advanced preclinical stages.
