Recombinant Protein Expression Service in Mammalian Cells

Service Package

For standard proteins, this is the service package of choice if you require limited quantities of recombinant protein expressed in mammalian cells for example for initial target characterisation or early stage production. Furthermore, the manufacturability and production data obtained from this service package can serve as a valuable starting point for future upscaled and/or refined production of your target protein.

If you have a challenging target, need a larger quantity or have any other project requirements, we are happy to fulfill them with our highly customized protein production services.

Recombinant Protein Expression in Mammalian Cells

Recombinant-Protein-Expression-Service-in-Mammalian-Cells_Process-Steps_trenzyme-GmbH

Protein Expression in Mammalian Cells – Service Package Includes

  • All steps from cloning to purification
  • Final yield: starting at 1 mg purified protein (more on request)
  • Final purity: > 90 %
  • Short processing time: 4 business weeks (for standard proteins) including cloning, expression, purification and QC
  • As starting material we can either use an existing expression vector construct from the client or start with codon-optimized gene synthesis (additional service option).
  • Small scale pilot study for evaluation of manufacturability – not needed for known targets
  • Delivery of test samples from pilot study if desired
  • Comprehensive datasheet

Additional service options:

  • Gene synthesis as starting point
  • Purchase of additionally produced protein
  • Extended Quality Control: e.g. mass spectrometry, endotoxin detection, Western Blot or ELISA
  • Low endotoxin purification and endotoxin removal (Kommt das weg?)

Free Feasibility Check and Pilot Study

During an initial free one-to-one consultation, our scientific experts will perform a feasibility check (e.g. literature check, database check, product check, etc.) on your protein sequence to define the ideal service strategy for your specific target.

To maximize efficiency and save you significant time and money, this service includes a small-scale pilot study. This is a preliminary assessment of whether the target protein can be expressed in E.coli and whether the purification process is feasible. Test samples to check the functionality and quality of the purified target protein in your hands are available on request.

The big advantage for you: After pilot-scale evaluation, we guarantee final yield, purity and timeline – you only pay for production if we succeed!

  • If your target sequence is identified as a feasible protein by our initial screening tools, we offer the standard recombinant protein expression in mammalian cells service package with guarantee.
  • If your target sequence has been identified as a challenging protein or you require high yield production (e.g. > 10 mg), we offer highly modular, customized solutions with or Custom Protein Production Service.

Recombinant Protein Expression in Mammalian Cells FAQs

My target protein should be glycosylated - which expression host do you recommend?

For generation of glycosylated proteins we offer different expression systems like Yeasts, insect cells (Baculo) or also mammalian cell lines. Depending on the nature of your target protein and your exact needs, we will propose the most suitable expression host and system for your project.

What starting materials are required to begin a project?

We only need the amino acid sequence or uniprot reference number of your desired protein.

Why does my protein show a higher (or lower) MW on SDS-PAGE or Western blot as calculated?

Posttranslational modifications like glycosylation or very rigid protein structures may have influences on protein properties and running behaviour. Sometimes proteins run higher, seldom lower and sometimes they run as a smear.
