Cell-Free expression kit

Use Synthelis Cell-free Technology
to produce your proteins

After more than 14 years of optimizing our proprietary cell-free expression system, we now offer you the benefit of our technology to produce your proteins of interest. With the Syn-Xpress™ kit, you have a ready-to-use reaction mastermix into which you simply add the DNA specific to the protein you want to produce. 

Simple, scalable, fast, and adaptable, welcome to the field of possibilities of Cell-free technology with Syn-Xpress™.

The Syn-Xpress™ kit contains :
– Mastermix
– Control plasmid
– Instructions for use

The kit is available in several formats: 
– 1 x 1mL or 20 x 50µL reactions
– 1 x 5mL or 100 x 50µL reactions

Other formats are available on request, for high-throughput screening or scale-up. When scaling up, system yields are linear. 

We can supply Syn-Xtract cell lysate or proteins only.
Please ask us if you have a specific requirement.

Why should you use CFPS technology ?

Cell-free protein synthesis (CFPS) is a technology developed in the 60s. Since this time the system has been intensively worked by many groups all over the world and was thus strongly improved. This tool is now recognized for offering unparalleled flexibility for fast, efficient and inexpensive production of any type of proteins. Cell-free technologies are used in many applications going non exhaustively from protein engineering, gene network prototyping, synthetic biology, library screening, biopharmaceutical production, point-of-care biomanufacturing…

In vitro protein production using CFPS is a good alternative to in vivo systems as in addition to be fast, CFPS is flexible, more consistent and easily scalable from few microliters to hundreds of liters. The open-nature of the system gives access to the cellular machinery and thus, allow to adjust the reaction parameters to the specificity of each protein and better control the transcription and / or translation reactions. In addition, specific reagents can be added to help the folding of the protein (oxido-reductive agents, isomerases, chaperones…).
