Protein Production Service

Escherichia coli (E. coli) offers a simple, fast, and cost-effective system for recombinant protein production. While it cannot perform complex eukaryotic post-translational modifications, advances like co-expression of chaperones and engineered strains providing a pro-disulfide bond environment have improved its capabilities. abm recommends E. coli for applications where modifications like glycosylation are not essential.

For proteins requiring mammalian post-translational modifications or complex folding (e.g., membrane proteins), the mammalian expression system is the best option. abm suggests its mammalian expression service for proteins with complex native folding and modifications crucial to the intended application.

Additional Info


  1. Disclaimer for intended use: All of abm's recombinant proteins are for research use only and not intended for therapeutic/diagnostic applications. abm is not liable for any violation (and associated repercussions) to the specified use of its entire suite of recombinant proteins.
  2. Disclaimer for 'E. coli' expression system: The choice of utilizing a prokaryotic expression system (Escherichia coli) for eukaryotic protein production is solely up to the discretion of the customer with respect to being aware of the limitations to the rendition of correct number and type of Post Translational Modifications (PTMs).
  3. Disclaimer for extra amino acids: abm does not guarantee that the recombinant protein product will be free of any additional amino acids residues. Cloning may lead to the insertion of some amino acids at either and/or the N and C-terminus of the recombinant protein product which in most cases, is innocuous to the stability/functionality of the recombinant protein.
  4. Disclaimer for turnaround time: Note that the turnaround time indicated above is our best estimate currently. Final turnaround time is subject to change depending on actual experimental conditions.
  5. Disclaimer for functionality: abm is not in a position to guarantee protein functionality.

  5. By default, a His tag will be used for purification purposes. Otherwise, additional charges apply and please provide a verified gene expression antibody along with a positive control.
  6. Charges for C112 and C113 determined after customer has reviewed report from C111 and requested for Phase II. An estimate can be provided during quotation process.

FAQs

For E. coli protein expression, is the purified protein delivered denatured or folded?
The protein will be purified without any denaturing steps but we cannot guarantee whether the protein is folded properly within the E. coli system.
