Process Development Services
With team of experienced scientists and proprietary development platform, GenScript provides custom services for upstream process development, ranging from optimizing cell growth, screening production media, defining feeding strategies, to studying clone stability, and further scale-up to pilot and commercial production. We also offer a thorough analysis of growth rate, subcultivation ratios, cell mass, and other parameters. Upon request, we can perform additional specific process optimization studies or employ our scaled-down models to predict cell performance.
GenScript offers services for purification process development. For downstream process, protein purification is typically conducted through affinity columns. We also offer other chromatographic methods including gel filtration, ion exchange, and hydrophobic interactions. The purification tags are removed via a specific protease if desired, and the protein is further purified by gel filtration.

Stable cell line development
GenScript is proud of offering its years of demonstrative and professional custom services in generation and selection of stable clones for protein production.
- Proprietary OptimumGene codon optimization technology significantly increased expression level in any system.
- Reliable DHFR system, used for many commercial products.
- Professional high-throughput screening platform.
- Strict protein expression stability and growth stability evaluation.
Robust and efficient production processes are crucial to the success of IND-Enabling studies and to the preservation of product competitiveness. GenScript's ‘Time & Quality-Balanced’ process development strategy, including using cell pool samples for purification preliminary development and cell culture process optimization, 3L samples for purification process optimization and formulation development, and 10/50L samples for process scale-up and purification process lock greatly shortens the process development timeline.
GenScript has developed a monoclonal antibody purification platform process that allows clients to quickly establish a production process with an overall recovery rate of around 70% and with acceptable product characteristics, process and product-related impurities. GenScript will customize the processes to meet the unique needs of each client. For example , in the case of biosimilars, GenScript has effective techniques and tools to change the distribution of product glycoforms and charge isomers.
