Bioprocessing Catalog Cell Lines
A cell line that maintains favorable growth and productivity characteristics is vital for biopharmaceutical manufacturing processes, whether you are producing monoclonal antibodies, recombinant proteins, or viral vectors for gene therapies. Our ready-to-use cell line systems can accelerate your upstream development by greatly reducing the time, cost, and risk of developing new cell lines. Our cell lines are rationally engineered and designed for compliant biomanufacturing.
Key features include:
- Fully traceable cell lines with comprehensive documentation
- cGMP banked and characterized
- Paired, optimized, and chemically defined media and feeds
- Comprehensive user protocols for efficient cell line development and seamless scale-up, supported by technical consultation
CHOZN® Platform for Production of Biologics and Recombinant Proteins
Our CHOZN® platform is a Chinese Hamster Ovary (CHO) mammalian cell expression system that allows for faster, simpler selection and scale-up of high-producing clones for production of biologics and therapeutic recombinant proteins. It includes:
- High-performing CHO cell lines
- Paired media and feeds
- Optimized expression vectors
- Robust protocols
Three CHOZN® cell lines are available:
- CHOZN® GS -/- cell line, enabling rapid cell line development without the need for amplification by MTX metabolic selection agent
- CHOZN® DHFR -/- cell line, enabling rapid cell line development by amplification via MTX metabolic selection agent
- CHOZN® CHO K1 cell line, enabling rapid cell line development with the metabolic selection agent of choice
Powered by CompoZr® Zinc Finger Nuclease (ZFN) technology, the well-known and widely adopted CHOZN® GS-/- cell line can help shorten cell line development time lines by up to eight weeks while ensuring excellent stability, with >75% of clones maintaining >70% titer of 60 generations.
Optimized expression vectors for the CHOZN® GS -/- cell line include:
- pCGS3.2 standard CHOZN® GS expression vector
- UCOE® GS expression vector using the chromatin opening UCOE® expression technology
