Why XtenCHO™?

XtenCHO™ is our property mammalian expression system specially designed for transient antibody production. It was developed from a highly productive Chinese Hamster Ovary (CHO) cell line. XtenCHO™ provides the best transfection efficiency and the highest expression yields in a short time period. Altogether, XtenCHO™ offers competitive performance and price compared to other expression systems on the market.
XtenCHO™ applications:

  • Drug discovery: XtenCHO™ allows the production of large quantities of antibodies in a short period of time, making it a reference expression system for the development of therapeutic antibodies
  • Protein engineering and research: Along with a rapid protein expression, XtenCHO™ provides a high-yield production important for screening different variants and testing several production conditions. Allowing for initial antibody characterization and improving their properties.


What is High Throughput Recombinant Antibody Production?

A recombinant antibody (RecAb) is an antibody produced using genetic engineering techniques without relying on animal use.
The high throughput production technology builds on this recombinant antibody production technique and offers a quick and robust solution for the production of tens or even hundreds of antibodies in parallel previously generated from programs like phage display, humanization, epitope mapping, and affinity maturation projects.
This technology fills a growing need in the pharmaceutical and biotechnology industries, particularly with regard to the selection and/or optimization of leads.


Applications of High Throughput Recombinant Antibody Production

High Throughput Recombinant Antibody offers a major breakthrough and allays the bottleneck regarding new drug discovery.

  • Biotherapeutics’ Discovery: HTP-RecAb can be a quick and easy way for preliminary screening and characterization of top candidates with cost-efficient production.
  •  Screening: HTP-RecAb allows for the simultaneous production of several and diverse antibodies. An HTP recombinant antibody production can aim to screen molecules in terms of their biophysical and pharmacokinetic properties.
  • Epitope Binning and Mapping: HTP-RecAb can be used to identify monoclonal antibodies that recognize distinct or overlapping epitopes on an antigen. This is of great importance as it allows the selection of the most optimal antibody in terms of effectiveness to target a specific therapeutic application.
  • Multi-Hybridoma Conversion: HTP-RecAb can also be applied to convert a large portfolio of hybridoma-produced monoclonal antibodies to recombinant production. This provides the benefit of batch-to-batch consistency, rapid and affordable production.
