Protein service

Request a quotation

Our expert team is specialized in protein production for downstream R&D applications (e.g. immunisation, functional assay, cristallography...)

  • From the molecular biology work to the production and purification, we can handle a part or the totality of your protein production projects
  • A project manager is dedicated to your project and can recommend an adapted project strategy
  • Committed to customer satisfaction, we can adapt our experimental procedures to your specific requirements

We take care of your protein production so that you can focus on your discovery.

 

Mammalian cell expression We offer either fast and high yield transient protein expression or constitutively expressed protein in monoclonal or polyclonal cell line. Our current capacities reach 5 liters batch.
 Transparency Weekly report to keep you informed about your project according to pre-defined milestones and Go/NoGo steps.
E. Coli expression Optimisation steps of expression conditions can be included in our E. Coli protein production service. Our fermentation capacities allow 1 to 8 l batch production. Reactivity Short turnaround time and high performance to speed up your discovery.
Purification The protein we produce can be down stream processed from sample preparation (harvesting, lysis, concentration, dialysis) to chromatography (AKTA FPLC). ISO 9001-2000 From project definition to final product or report each step is quality monitored.
Quality control Quality control could include SDS PAGE, Western Blotting, ELISA, etc. QC could be performed independently from protein production project. Strict confidentiality policy
