    Customize DNA constructs (eGene) with pre-set fusion tags to optimize protein expression

    Nuclera has developed eGeneâ„¢ Prep Kits to rapidly convert your Gene of Interest into expression cassettes that are immediately compatible with eProtein Discoveryâ„¢ reagents for Cell-Free Protein Synthesis (CFPS). CFPS utilizes linear DNAs (eGeneâ„¢ constructs) as one of its ingredients to power the cell-free machinery to produce protein.

Frequently Asked Questions

Yield is protein dependent and can range from micrograms to low milligrams.

Tube scale protein expression takes a day, similar to the time it takes to screen proteins on the cartridge.

Cell free protein expression or Cell Free Protein Synthesis (CFPS) is a technique which enables protein expression in vitro, without the need for living cells. By combining the DNA construct corresponding to your protein of interest, cofactors, substrates and energy systems, functional target proteins can be generated in a matter of hours.

Generating linear expression DNA constructs involves PCR, PCR cleanup and diluting DNA to the required concentration.

Yes, other solubility tags sequences can be added to the Gene of Interest, with appropriate linker in place.

Yes, you can add tags in the Gene of Interest sequence however, you cannot test purifiability with the optional tags on the cartridge.

Yes, additional tag sequences can be added, with the appropriate linkers in place.

Yes, instrument training is provided upon installation. We have a dedicated technical support team that is available to answer your questions and help troubleshoot.
