Gene Therapy Starting Raw Material Preparation

Starting raw materials in gene therapy are the base materials, such as plasmid DNA, viral seed lots, and cell banks, that are used in the production of gene therapy products. These materials directly affect the quality and safety of the final product. Relying on an advanced technology platform and a team of experienced experts, CD Formulation provides high-quality and reliable gene therapy starting raw materials, such as plasmid DNA, viral seed batches, cell libraries, etc., through strict quality control to ensure their purity, stability, and biological activity. We also provide comprehensive raw material risk assessment and quality control services to ensure that no viruses or other contaminants are introduced into the raw materials during the production process.

Why Conduct Gene Therapy Starting Raw Material Preparation?

• Ensure product quality. Starting materials are the foundation of gene therapy products, and their quality has a direct impact on the safety, efficacy, and consistency of the final product. High-quality starting materials help minimize the risk of failure in the later stages of product development.
• Comply with regulatory requirements. Regulatory agencies have strict requirements for raw materials for gene therapy products, including their source, purity, identity, and quality control.
• Risk management. In gene therapy, raw materials can pose potential risks, such as viral contamination and endotoxin contamination. Through rigorous preparation of starting raw materials, these risks can be identified and managed to ensure product safety.
• Facilitate process development. Good preparation for starting raw materials can help optimize the production process and improve productivity and the feasibility of large-scale production, thereby reducing costs and accelerating product launches.

Our Services for Gene Therapy Starting Raw Material Preparation

Gene Therapy Plasmid DNA Preparation

We provide plasmid DNA preparation to ensure the safety of plasmids for gene therapy applications. In plasmid design, we remove non-essential genes and tumorigenic elements to avoid the safety risk of recombination caused by homologous sequences. Combined with the selection and mechanism of action of viral vectors, we provide the basis for the modification of plasmid and viral vector virulence genes, viral insertion or replication regulation-related element sequences from the source and function of the constituent elements such as screened genes, expression regulatory elements, coding sequences, etc. We specify the process of plasmid construction and confirm the corresponding results. In this quality control, we provide tests including identification, content, plasmid integrity, confirmation of important gene sequences, purity, host cell DNA residue, host cell protein residue, sterility, endotoxin, and so on.

Bacterial seed lot preparation

Bacterial seed lots are the original bacterial strains used to produce plasmid DNA or other biologics. These bacterial strains are screened and validated to ensure that their genetic characteristics and production capabilities meet the production requirements. Bacterial seed lot preparation is an important part of the production of biopharmaceutical and gene therapy products, and its purpose is to provide stable and reliable starting materials for large-scale production. Ensuring the quality and consistency of bacterial seed lots provides reliable starting materials for subsequent biologics production. Strict quality control is required for the preparation of bacterial seed lots, which generally includes colony morphology, staining microscopy, biochemical characteristics, antibiotic resistance check, purity, electron microscopy, bacteria, fungi, phage, and so on. The genetic and phenotypic stability of the seed lot should be able to meet the needs of gene therapy research.

Viral seed lot preparation

Viral seed lot refers to the original viral material used for the production of viral vectors. The management of viral seed lot, preparation is the starting point of viral vector production, which is used to expand the production to obtain a sufficient number of viral particles for gene therapy. Quality control of viral seed lots generally includes identification, viral titer, phenotypic characterization, gene sequence identity, transcription/expression of therapeutic sequences, biological activity of therapeutic sequences or expression products, sterility check, mycoplasma check, and exogenous viral factors. Specific exogenous viral factors that may have been introduced during historical transmission and construction of the seed lot should also be tested.
