OUR TECHNOLOGY

A rapid protein prototyping platform combining cell-free protein expression with digital microfluidics

Nuclera's eProtein Discovery™ places rapid protein prototyping technology at your fingertips so you can make progress on your protein projects.

Time and resources are on your side

There is an urgent, ever-expanding need for generating soluble and active proteins to be used for downstream high throughput screening in drug discovery. Obtaining soluble protein constructs using cell based approaches can be time-consuming, costly, and requires tremendous resources. We make this easy by combining unique cell-free technologies and novel digital microfluidics, turning protein access into a Pipette and Forget^TM workflow that transforms weeks into days.

Speed up target identification

Simultaneously analyze constructs, expression conditions and purifiability to find the winners for scale up.

eProtein Discovery™: How the protein prototyping platform works

Cell-free Protein Synthesis

Speed-up target discovery with eProtein Discovery^TM! Our technology benefits from the advantages of complex cellular systems while bypassing lengthy, resource-consuming steps.

By utilizing cell extract derived reagents, proteins get synthesized in a droplet on our smart cartridge or in a tube. Screen 8 distinct expression conditions all at once. Each reaction includes purified cellular machinery, your carefully designed DNA construct, and the cofactors, substrates, and energy systems needed to screen for optimal expressing conditions.

Take high throughput bioreactors, liquid handlers and purification columns out of the equation. Optimal expression conditions identified in a day with our cell free protein synthesis solution!

Protein Detection

When you convert the cDNA for your protein of interest into an eProtein Discovery™ ready construct with our eGene™ Prep Kit, a sequence coding for a small peptide detection tag is installed.

After expression of the eGene™ on the instrument, a detector protein is added that binds to the detection tag and becomes fluorescent. The optical system within the instrument measures fluorescence intensity and converts the reading into what matters to you - protein concentration.

Microfluidics-based Smart Cartridges

eProtein Discovery^TM operates with a digital microfluidics lab-on-a-cartridge designed to allow droplets of DNA to split, mix, and move within the smart cartridge.

Based on rapid digital signals, and with the help of eProtein Discovery^TM reagents, our software-controlled technology effectively turns DNA constructs into proteins for further characterization.

Covering 8 cell-free expression systems, our programmable microfluidics-based smart cartridges provide the features of complex cellular machinery with minimal time, effort, and resources.

Software and eProtein^TM Report

Software and eProtein Discovery™ Report

eProtein Discovery^TM comes with software optimized for the instrument’s touchscreen interface. While providing clear instructions, the screen also allows you to monitor each step of your run in real-time.

Following your run, receive an auto-generated report (also available for export), including solubility, soluble yield, and purifiability through the eProtein^TM report for pre-selecting the most promising candidate to scale up.
