Inproteo Licenses His Tag Patent to Pierce Biotechnology

NEW YORK, Oct. 29 (GenomeWeb News) - Inproteo, the organization previously known as the Indiana Proteomics Consortium, has licensed a US patent for the His Tag fusion protein purification technique to Pierce Biotechnology, the organizations said today.


The patent, number 4,569,794, is entitled, "Process for purifying proteins and compounds useful in such process," and describes a process in which a precursor of a biologically active protein or polypeptide is separated from a mixture that contains immobilized metal ions. It was granted in 1986 and originally assigned to Eli Lilly, which is one of the partners in Inproteo.


The license covers past and future use of the technology over the life of the patent, and "allows Pierce to supply licensed products to their customers for research purposes," said John Hurrell, President of Inproteo, in a statement.


Inproteo,  founded in 2002, is a partnership between Indiana University, Purdue University and Eli Lilly that focuses on the development of novel proteomic discovery tools and methods.
