Purtein LLC has developed a protein purification technique for simply and cost-effectively isolating proteins from a superfamily of proteins sharing a common structural topology. The company has also developed a protein tag from a fragment of one of these proteins that can be used to simply and inexpensively purify a recombinant fusion protein composed of the tag and any target protein of interest. It also has a quantitative ELISA for the tag.

We are pleased to announce that Purtein has successfully expressed and purified a fusion protein in E.Coli and CHO cells using its technology.

Purtein is developing a kit for the purification and quantification of fusion proteins using its tag. This will be marketed to research laboratories. The company will also license its technology to biotechnology and pharmaceutical companies.

Purtein’s original patent was authored by Elliott Bedows and Jason A. Wilken. The technology is being further developed by Elliott Bedows, Tom McDonald, David Smith and Annika Weber of the University of Nebraska Medical Centre.
