Transfected Stable Cell Lines
Reliable | High-Performance | Wide Rage
Precision reporter, kinase, immune receptor, biosimilar, Cas9, and knockout stable cell lines for diverse applications.
In the rapidly evolving field of gene and cell therapy, viral vectors are the core delivery tools that directly impact the safety, efficacy, and clinical viability of advanced therapies. Backed by years of technical expertise and dedicated GMP-compliant infrastructure, Creative Biogene has established an integrated, end-to-end GMP viral vector CDMO platform. This platform supports lentivirus, retrovirus, adenovirus, and adeno-associated virus(AAV)production, providing complete lifecycle support from process development to GMP-grade production and regulatory submissions.
Our GMP-grade viral vector platform is designed to meet global regulatory expectations, including those of the FDA, EMA, NMPA, and WHO. Facilities are equipped with ISO 5–7(Grade A–C)cleanrooms under BSL-2 compliance, supporting both adherent and suspension-based manufacturing systems. With upstream bioreactor capacities up to 200 L and downstream aseptic fill-finish capabilities, we operate a fully closed and traceable production system with comprehensive documentation, including batch manufacturing records(BMR), certificates of analysis(CoA), and method validation reports.
We offer three distinct production grades tailored to each development phase:
PRECLINICAL
IND
CLINICAL TRIALS
BLA
COMMERCIAL
Research-grade
GMP-like
GMP-grade

GMP Lentivirus Production Service
Lentiviruses are enveloped RNA viruses capable of integrating into the host genome, offering stable, long-term expression even in non-dividing cells. With high packaging capacity(~8–10 kb), they are suitable for delivering large payloads, CRISPR/Cas systems, and multicistronic constructs. They are widely used in CAR-T, NK cell therapies, iPSC editing, and gene modulation studies.

Creative Biogene supports multiple serotypes including AAV2, AAV5, AAV8, AAV9, and engineered variants. Production is conducted in HEK293 suspension cultures, with scalable output up to 1017 GC per batch. Downstream processes include affinity chromatography, ion exchange, and density gradient centrifugation.

Retroviruses, especiallyγ-retroviruses like MMLV and MSCV, remain valuable for gene modification in dividing cells such as HSPCs, T cells, and tumor cell lines. These vectors integrate into host DNA, making them suitable for long-term, stable gene expression. We support PG13-derived packaging cell systems with stable expression and MSCV vectors optimized for stem cells, offering resistance to epigenetic silencing and enhanced expression in iPSCs and ESCs.

Creative Biogene provides both replication-defective and helper-dependent(gutless)adenoviral vectors. Our platform supports scalable production in HEK293 or PER. C6 suspension systems with advanced purification strategies including CsCl gradient, chromatography-based methods, and ultrafiltration.
Creative Biogene provides a flexible and robust GMP production ecosystem, segmented into functional service modules.

Whether you're launching a discovery-phase study or preparing for clinical submission, our team stands ready to support your success with flexible solutions, expert guidance, and manufacturing excellence.
Q: How does Creative Biogene ensure regulatory alignment across FDA, EMA, and NMPA requirements?
A: Our quality system is built upon global standards including ICH Q7, ICH Q5A, and FDA 21 CFR 210/211, ensuring full compliance for U. S. , EU, and China submissions. All process documents, analytical methods, and batch records are prepared in eCTD-ready formats. We have extensive experience supporting IND, CTA, and IMPD filings for both AAV and LVV platforms, and provide Module 3 authoring along with regulatory response services. Our embedded QA team facilitates customer quality verification(CQV)and supports flexible change control, on-site audits, and timely response to regulatory inquiries.
Q: How do you ensure a seamless transition from preclinical to GMP manufacturing?
A: We implement a staged capacity model tailored to clinical progression—≤50L for preclinical(adherent system), 50–200L for early trials(single-use bioreactors), and≥200L for late-stage or commercial production(suspension platform with GMP fill-finish). All viral vector platforms adopt standardized suspension-based processes, with scalability parameters validated in advance. Our dedicated teams oversee process characterization(PC)and PPQ with typical timelines of 8–10 months. In addition, our internal plasmid platform ensures critical raw materials are supplied in-house, and dual-sourcing strategies mitigate global supply risks.
Q: Is Creative Biogene financially stable enough to support long-term projects?
A: Yes. Creative Biogene operates independent R&D and GMP manufacturing facilities across North America and Asia. We deliver over 100 GMP viral vector batches annually, serving top-20 pharmaceutical companies and innovative biotechs. Our integrated service model spans plasmid production, cell banking, viral vector manufacturing, and CMC support, with a client retention rate exceeding 70%. We maintain active legal, QA, and risk control teams, and offer business continuity protections in all contracts to ensure delivery consistency and project security.
