CHO Edge System
Integrating genetic tools and data-driven models to routinely achieve titers of 8–11 g/L across modalities

Titer and product quality can vary significantly across molecules when using the same expression vector. Asimov’s CHO Edge System enables smarter exploration of vector designs by integrating our proprietary GS knock-out CHO host, hyperactive transposase, >1000 characterized genetic elements, and advanced computational tools.

System performance
Exploring vector design space
Selection stringency, heavy-chain/light-chain ratio, signal peptide pairings, and codon optimization all uniquely influence the expression of different molecules. Figure: Stable pool titers for four different molecules from six vector designs; the optimal vector design is unique to the molecule.

High titers across modalities
The CHO Edge System routinely achieves 8-11 g/L clones across biologic modalities, including IgG monoclonal antibodies as well as 2-chain, 3-chain, and 4-chain bispecifics. Figure: Top 12 clones for six different molecules analyzed in a 14 day Ambr® 15 platform process.

Highly stable clones
Transposase-mediated integration drives >80% titer stability over 75 generations. Figure: Average relative titer of 5-7 clones per molecule across 4 different molecules.

System Licensing
By licensing Asimov’s CHO Edge System you’ll gain access to our suite of technologies for commercial-grade cell line development in your lab.
Expand the boxes below to learn more.
Host cell lines
We developed a glutamine synthetase (GS) knock-out cell line for producing antibodies, multispecifics, and other protein modalities.
To enable glycan engineering, we also generated a GS/fucosyltransferase (FUT8) double knock-out line that yields 100% afucosylated antibodies with a 10-fold boost in antibody-dependent cellular cytotoxicity (ADCC).

Genetic parts library and hyperactive transposase
We have developed a hyperactive transposase and a library of >1000 characterized genetic parts for use in CHO cell line development. These genetic parts span different cell functions, including promoters, untranslated regions, epigenetic insulators, signal peptides, polyadenylation signals, inducible systems, genome editors, and more.

Computer-aided vector design with Kernel
Asimov's computer-aided design (CAD) software, Kernel, can be used to optimize vector designs. It achieves this through the use of our proprietary biophysical/AI models of transcription, translation, secretion, and more.

CHO Edge System
Cell line development services
Our experienced team uses the CHO Edge System and state-of-the-art equipment to perform CLD.
Reduce the risk of a low titer cell line
- With our CHO Edge System, titers are typically 8-11 g/L or higher for both IgG monoclonal antibodies and more complex bispecific architectures.
5 g/L or it's free
- We guarantee high titer cell lines for monoclonal antibodies. If the RCB generated for a mAb is under 5 g/L, the CLD campaign and all commercial use rights are free.
Regulator approved
- IND approved system and a team with decades of experience in CLD and product commercialization.
How it works

We use our proprietary software, Kernel, for codon optimization, vector design, and biophysical simulation to make a panel of expression vectors.
You request a cell line development campaign for a specific biologic and provide us with an amino acid sequence.
