Cell Line Development Services - Abzena

Cell Line Development

Our AbZelectPRO™ cell line development solution can rapidly progress your therapeutic protein and recombinant vaccine program from DNA to RCB in 10 weeks.

Leverage our enhanced technologies and extensive cell line development experience.

At Abzena we understand the importance of optimal cell line development (CLD). With over 20 years of expertise and a commitment to quality excellence, we can reduce time to market. Our fully integrated, proprietary  AbZelectPRO™ platform allows us to accelerate timelines and de-risk CLD programs, efficiently enabling the rapid delivery of productive cell lines for your complex biologic or bioconjugate.

Generation of early-stage product from fast stable pools enables us to confirm the Quality Target Product Profile (QTPP). In parallel, this material can be used to initiate formulation development and analytical method development, taking these key activities off the critical path. Material from stable pools can also help accelerate process development for antibody-drug conjugates.

We have developed multiple cell lines that have progressed from process development into manufacture and through clinical trials. With years of experience in providing cell line development services, our team has successfully expressed biologics including antibodies, antibody fragments, bispecific antibodies, fusion proteins, growth factors and vaccines.

Improving Cell Line Development Efficiency

Enhanced cell line development provides the foundation of biopharmaceutical development success and mitigates risk. For molecules such as mAbs, Fabs and Fc fusions, Abzena minimize timelines using our AbZelectPRO™ platform methodology. For novel and complex molecules, our AbZelectPRO™ platform allows us to design and develop a rapid, robust approach to your program.

Our Integrated Approach to Cell Line Development

AbZelectPRO™: Enhanced Cell Line Development - Abzena

We have an integrated cell line development approach which shortens timelines to IND enabling material. This is supported by using fast stable pools to generate early-stage material for characterization, pre-formulation, analytics and lead molecule selection. We do this through:

  • Fast development of high-quality clones for manufacture
  • Platform processes for rapid progression through process development
  • Use of widely available commercial media and feeds for easier transfer
  • Strong analytics and bioassay capabilities to ensure product quality as well as productivity
  • Global project management to ensure the smooth progression of projects for on-time delivery

Abzena's AbZelectPRO™ CHO Platform

We use well-established platform methodology that reliably delivers product quality within predictable timelines.

Our AbZelectPRO™ (ABZ-CHO-K1) CHO cell line offers:

  • Highly productive, fast stable pools within 5 weeks of transfection for production
  • Serum-free, suspension-adapted CHO cells
  • Well-documented history of ABZ-CHO-K1 cell line including Research, Master, and Working cell banks
  • Optimized 2G UNic vector to maximize gene expression
  • One cell line for a product’s entire lifecycle, from development through to commercial manufacturing
  • Purified early-stage material for formulation and analytical method development, reducing development timelines
  • High throughput clone screening to rapidly identify highly productive clones
  • Quick, reliable process to generate clonal RCBs within 10 weeks of transfection
  • Rapid progression of RCBs through process development to GMP scale-up to provide IND enabling material

Enhanced AbZelectPRO™ platform with 2G UNic by ProteoNic

Benefits of AbZelectPRO™ with 2G UNic vector technology:

For more complex biologic programs, we can deliver increased productivity by enhancing our AbZelectPRO™ platform, which combines our existing CHO cell line with ProteoNic’s premium expression vector technology 2G UNic.

  • Optimized expression cassettes to maximize productivity from each cell
  • Efficient GS selection marker compatible with current AbZelectPRO™ CHO Cell Line
  • Proven track record – ProteoNic are moving towards regulatory approvals with multiple programs in the clinic and work with several large pharmaceutical firms.
  • Early material from highly productive stable pools for antibodies, bispecifics and fusion proteins
  • Higher frequency of high-producing clones offering more shots on goal- up to 8 g/L
  • Highly stable clones maintaining productivity beyond 60 generations
  • Uses single-use bioreactors to lower production costs
  • Robust scalable and consistent platform process
  • Further process optimization can boost titres to achieve 10g/L at scale
  • Enhanced cycle times with faster growth with optimized CHO-K1 host cell line

How it works:

ProteoNic’s 2G UNic technology uses the combined effect of novel genetic elements to exert a positive effect on recombinant protein production levels and boosts the performance of other expression-enhancing technologies.  This state-of-the art vector technology also increases production levels of difficult-to-produce complex protein, including bispecifics and fusion proteins as well as levels of products already in the multiple g/L range.

Technical Evaluation of our Enhanced AbZelectPRO™ Platform:

  • 3x higher stable pool productivity for antibodies and fusion proteins
  • Higher frequency of high-producing clones offering more shots on goal
  • High number of high-producing clones >5 g/L
  • 100% of selected clones stable after 60 generations

Cell Line Development for Biosimilars

We can help you maintain biosimilarity, critical for the regulatory approval of biosimilar products, by developing your cell line using the originator cell type. We have access to a range of CHO, NS0 and Sp2/0 cell lines adapted to serum-free growth media.

Our cell line development experts de-risk your project by providing additional product quality assessments to ensure that the Quality Target Product Profile (QTPP) is on track to match originators. Additional early upstream process development can be performed using 15 or 250 ml multi-parallel robotic bioreactor systems to better match originator CQAs.

Whether you decide to stay with the originator or switch to a new host cell line, Abzena can advise on strategies for clone selection, process development and comparability studies to demonstrate that critical quality attributes affecting efficacy and safety are maintained.

We offer comprehensive analytical and bioassay packages to support clone selection minimizing process development time.

Vaccines

Applying our platform technologies and extensive experience in proteomics, protein engineering, bioconjugation and formulation development, we design novel subunit and conjugate vaccine candidates.

Underpinned by our analytics capabilities, protein expression, scale up and manufacture services we ensure that your vaccine is successfully delivered to IND for clinical trial evaluation.

Other Cell Lines

We have the flexibility and expertise to apply our processes to other proprietary host cell lines to support your program.

For example:

  • SP2-0
  • NS0
  • PER.C6
  • CHO-ZN
  • CHO BIOP3

Research Cell Banking

From transfection pools or non-clonal cell lines we apply our robust single cell cloning process to rapidly isolate and identify the most productive monoclonal populations.

Our services include:

  • Single cloning step for rapid generation of monoclonal populations
  • High statistical probability of monoclonality with visual images to provide documented assurance
  • Integrated product quality assessment included in clone selection
  • Storage in validated auto-fill liquid nitrogen Dewar with an independent validated monitoring system with a 24-hour call out.
  • Back-up cryo-storage capacity is permanently available, ensuring a robust and reliable service.
