Your benefits from working with us

Guarantee – Pay Only When We Succeed!

We guarantee the final quantity and purity of your desired target protein in the given timeframe. You only pay when we succeed!

All-inclusive Service Package

We provide a high quality service package for recombinant protein expression in mammalian cells. Everything from cloning to final protein purification is included in a fixed price.

Transparency & High Quality

Our dedicated project management will guide your project through every step of the process and keep you constantly informed on the progress. Transparency and high quality service are our mission.

Free Feasibility Analysis & Consulting

Our free feasibility check of your protein sequence is the basis for our free individual consultation with you to define the ideal service strategy for your target that will lead to success.

Free Feasibility Check

During initial free individual consulting, our scientific experts run a feasibility check (e.g. literature check, database check, product check, etc.) with your protein sequence to define the ideal service strategy for your specific target:


  • If your target sequence is determined by our initial check tools as feasible protein, we offer the guaranteed service package.
  • If your target sequence is determined as demanding protein or you requested a high yield production (> 10 mg), we offer highly modular custom-tailored solutions.

Mammalian Expression 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.
