1-Step In vitro Protein Expression Kits

Express proteins in one step

By Douglas Hayworth

Our human in vitro translation system is the ideal choice when traditional protein expression methods are unsuccessful and for difficult-to-express proteins.

Thermo Scientific Human In Vitro Protein Expression Reagents and Kits enable cell-free translation and post-transcriptional modification of full-length proteins from mRNA or plasmid templates. One-step, high-yield and “heavy-mass” varieties of kits are offered, as well as the essential cloning vectors and custom cloning service.


  • Flexible – choose a system for microgram- or milligram-scale expression
  • Fast – express functional proteins in one step
  • Functional – use a human expression system to reflect human biology
