Revvity’s CHOSOURCE™ Glutamine Synthetase (GS) knockout cell line is a well-established, cGMP-manufactured CHO-K1-derived suspension cell line.
ProteoNic’s 2G UNic® vector boosts CHO cell protein yields by enhancing transcription, translation, and stability – enabling high titers and rapid cell line development.
* A Strategic Partner Fee is applicable if/when license holder transfers asset to another party.
AbZelectPRO™ streamlines stable cell line development, enhances efficiency, and cuts timelines to IND application. Tailored for small to midsize biotechnology companies with antibody-based therapeutics, AbZelectPRO™ combines our existing CHO-K1 cell line with ProteoNic’s premium expression vector technology 2G UNic. It has been designed to accommodate diverse modalities and is supported by our strong analytical expertise.
Two next-generation Glutamine Synthetase (“GS”) knockout CHO-K1 expression systems, including a double knockout ADCC+ platform for afucosylated proteins are available, These further enhance speed, scalability, and flexibility for our biopharma customers. AbZelectPRO™-KO and AbZelectPRO™-KO+, are our GS knockout platforms. They are available as a standalone cell line development offering or as a fully integrated GMP program, with fully transparent pricing to IND with no royalty fees.

We have over 20 years of experience in delivering solutions at each stage of the development lifecycle from early-stage research and discovery, through lead candidate selection, and onward into process development and GMP manufacture.
Unlike most other service providers, we can provide technical and scientific support that truly spans early-stage research through process development and GMP manufacturing under a single organization to better ensure that the TPP can be achieved. Our global scientific teams have extensive experience in overcoming some of the most challenging and complex biologic and bioconjugate programs, making us the perfect partner for novel and disruptive technologies that other biopharmaceutical CDMOs may shy away from.
Our experienced team is focused on getting it right from the start. We identify and address challenges early in drug design to better ensure downstream clinical and commercial success. We also have expertise in fixing and optimizing drugs in later stage development to rescue them from the drug development graveyard.
With capabilities ranging from bioassays to cell line development, bioconjugation and clinical and commercial manufacturing, all under one organization, we can reduce the white space in the development path, which ultimately minimizes risk, reduces costs and accelerates timelines for our customers.
As an integrated service provider, we accelerate timelines through the ease of technical and materials transfer, and improved scheduling. Better workflows and processes can also be attained through improved knowledge transfer between internal multidisciplinary experts and the development of a deep understanding of the drug as it progresses from target to lead selection and process development and manufacture.
Our team is always seeking new ways to innovate and streamline development for our customers. Our extensive scientific capabilities and proprietary solutions like EpiScreen® 2.0, Composite Proteins™, Composite Human Antibodies™, AbZelectPRO™, ThioBridge™, and LabZient™ are designed to give your program the best chance of clinical and commercial success.
