Stable cell lines, stronger starts
The right expression platform is fundamental to future therapeutic success, creating opportunities to reduce manufacturing costs and ensure consistent product quality. We offer a robust platform for cell line development with our portfolio of expression systems and cell line engineering services, providing the freedom you need to accelerate therapeutics to first-in-human studies.
The CHOSOURCE expression platform contains a well-established GS KO cell line, a glycoengineered ADCC+ cell line, and TnT transposon vector, plus flexible licensing terms, to help streamline development and manufacturing processes.
Custom editing services support specific manufacturing needs for protein and viral vector therapeutics, backed by over 10 years of experience in gene editing for biotherapeutic manufacturing.
Our new beta program supports developers looking to improve vector manufacturability.

Clone selection and characterization
Reliable accuracy, streamlined workflows
Reliable accuracy, streamlined workflows
Address bottlenecks within clone selection and characterization with regulatory-compliant platforms that reduce resource intensity and provide assay consistency.
Our cell counters and image cytometers can evaluate thousands of clones through automated processes so you can quickly assess cell viability, determine transfection efficiency, monitor growth, identify single colonies, and achieve high-throughput hit selection.

Quality assurance and quality control
Test with confidence, deliver with trust
Test with confidence, deliver with trust
We offer tools to help you characterize your therapeutic research at every step of the bioprocessing development workflow. Through innovative, robust platforms, reliable and sensitive assays, and reagents produced with strict manufacturing practices, we provide you with confidence in your product.
Identify impurities through our range of host cell contamination detection assays and technologies, evaluate plasmid integrity rapidly with our microfluidics platform, and assess functionality with reduced time and effort using our no-wash AlphaLISATM and HTRFTM assays.

Scale up and manufacturing
Compliant foundations, consistent results
Compliant foundations, consistent results
When looking to scale up your therapeutic research, turn to our innovative platforms and reagents that can help ensure you transition your workflow as simply and effortlessly as possible.
Our GMP reagents are manufactured under controlled, traceable, and consistent workflows and are fully compliant with regulatory standards. These reagents are supported by strict documentation and released with independent quality oversight. Furthermore, our integrated automation systems have been continuously developed over the last 30+ years to provide you with benefits in throughput, capacity, and format selection, and can help reduce the risk of late-stage setbacks.
