Calixar and Synthelis partner to provide membrane protein services

18 July 2012

Two French companies specialising in membrane proteins, Calixar and Synthelis, have entered into an alliance for the production and isolation of all types of target membrane proteins.

Calixar specializes in the isolation and crystallization of native and functional membrane proteins, and Synthelis, specializes in the production and vectorization of these molecules.

The results of this collaboration will have applications ranging from the development of antibodies to the discovery of new drugs, including the determination of the structure of these targets and vaccine formulations.

Instead of trying to produce these proteins themselves, customers will be given access to state-of-the-art production and purification technologies, enabling them to concentrate on their core activities. Furthermore, the companies say, thanks to the critical mass of skills and technologies made available to them, they will be assured of obtaining targets in their native conformation, thus guaranteeing the success of their programs for developing new drugs, vaccines and therapeutic antibodies.

The agreement provides for Synthelis to utilize its molecular biology know-how, deployed in multi-expression-systems and functional characterization configuration, to underpin the production phase. Calixar will be responsible for the possible upstream identification and subsequent isolation, purification, stabilization and crystallization of targeted membrane proteins.

Calixar’s technology has already been validated in some 20 targets (including GPCR receptors, ionic channels, transporters and viral proteins) and its unique approach makes it possible to preserve the native conformation of membrane proteins in solution after their extraction and purification from any biological system.

“We have been undertaking joint R&D programs since the end of 2011, which has confirmed that our two companies have very complementary expertise,” said the president and co-founder of Calixar, Emmanuel Dejean. “We now want our customers to benefit from this critical mass of know-how and technology, which no other company currently offers in Europe.”

“Through this alliance, the two companies are strengthening every aspect of their business, not only their commercial clout, technical expertise and visibility but also their ability to innovate in their quest to find answers to complex sets of problems with great potential,” said the president and co-founder of Synthelis, Bruno Tillier. “This partnership also has an impact on the research structure in the Lyon-Grenoble area as the two companies are based in the region.”
