Safe, Reliable Cell and Viral Banks

Reliable CGMP cell and viral banking secure the starting materials behind consistent viral vector manufacturing. Well-characterized master and working banks improve traceability, supporting comparability across batches, provide a controlled foundation from IND through commercialization.

Master cell banks (MCBs) and master viral banks (MVBs) are the original, fully characterized sources used to establish your production system. Working cell banks (WCBs) and Working Viral Banks (WVBs) are derived from the master bank and used directly in routine manufacturing under controlled CGMP conditions. They require stringent CGMP conditions to maintain integrity and traceability across batches.

CGMP-compliant storage preserves cells and viral banks under validated conditions with continuous monitoring, security, and backup systems in place. This helps protect bank integrity over time, reduces supply chain risks, and keeps critical starting materials available as manufacturing resumes or scales.

Outsourcing gives teams access to specialized facilities, validated procedures, and regulatory expertise without building that infrastructure in-house. A qualified CDMO can also align bank production, testing, storage, and inventory control, reduce handoffs, and improve readiness across development.

SK pharmteco supports CGMP master and working cell and viral banks with production, testing, storage, and inventory management as standalone services or within integrated viral vector manufacturing programs. Our dedicated viral vector infrastructure and quality systems help protect material integrity and support long-term manufacturing success.
