What is Recombinant Protein Production?

Charles River offers custom recombinant protein production services of high-quality recombinant proteins for all down-stream requirements. These may include, but are not limited to, biological assays or biophysical assays, in vivo studies, and structural solutions.

Our team of Protein Production Scientists are experts in engineering, focusing on challenging proteins that have little-to-no existing literature. The team designs constructs with a "right the first time" ethos, relying on their experience of successfully generating large quantities of crystallographic-grade proteins.

Breakthrough LINE-1 Reverse Transciptase Structure Published In Nature
Charles River protein scientists and crystallographers, as part of a global coordinated academic and industry effort led by ROME Therapeutics and Dr. Marty Taylor at Massachusetts General Hospital, have produced the first-ever high-resolution structure of LINE-1 reverse transcriptase (RT) using X-ray crystallography.

We then couple the most suitable recombinant protein expression host with multi-parameter studies to optimize the soluble protein yield, before progressing to large-scale production.

Utilizing automated protein purification service platforms, our aim is to purify your expressed protein as quickly as possible. Working as part of a multi-disciplinary Structural Biology team, we pride ourselves on our ability to deliver high quality crystallographic grade (>95 % purity) protein with the required pattern of post-translational modifications at the desired yield. We are experienced at working to low levels of endotoxin, a critical requirement for in vivo preparations.

We have a comprehensive suite of protein characterization techniques available in our lab, enabling monitoring throughout production (if required) or QC of fresh proteins post-production. We also offer protein characterization services for client-provided proteins.

Available Protein Expression and Purification Services:

  • Construct design / protein engineering
  • Multi-parallel construct generation
  • Protein expression using E. coli, mammalian, insect cells-baculovirus, and BacMam
  • Scalability from bench to fermenter scale (up to 20 L)
