Products and services

A world reference in
native membrane protein isolation

CALIXAR delivers the highest-quality membrane proteins used for (bio)drug discovery. Our products and services are adapted to pharmaceutical companies, biotechnology companies, as well as academic teams that are involved in life science. 

Our membrane proteins are among the best in the world for developing antibodies, formulating vaccines and/or discovering primary leads through Structure-Based Drug Design or High Throughput Screening assays.

Purified membrane proteins and customized detergents

CALIXAR has developed surfactant-based detergents that maintain the functional and structural integrity of membrane proteins. Our technology is unique as we do not require refolding, mutagenesis, truncation, or fusion. Our patented technology has a significant impact on membrane protein’s conformity and quality.

Membrane protein discovery, production and validation

CALIXAR guides its clients for defining the best  expression systems or relevant primary cells for specific targets. Our technology is crucial to the success of discovery programs and we also provide assistance to ensure that the expression system of choice is well aligned with the biological questions that need to be addressed.


New membrane protein discovery

CALIXAR’s technology is capable of producing high quality, native, wild-type, unaltered, unmutated and untruncated targets for antibody development and drug discovery projects. We are unique in the market and are at the forefront of Membrane Protein technology.

Due to our patented technology and expertise, we are able to manufacture membrane proteins that sustain the structure and function of the target. Our membrane proteins are pure, native, unaltered and stable. They are also able to bind to a wide and broad scope of compounds including agonists, antagonists, and allosteric modulators.

Gain exclusivity with our technology to compose your very own and unique customized membrane proteins. CALIXAR’s technology can equip you with unique targets for your biotech projects found nowhere else in the world.


A unique and native process

Conventional approaches tend to modify the protein through deletions or point mutations to make it adapted to the environment. Instead, CALIXAR’s approach modifies the chemical environment that will adapt to the proteins/antigens chemistry.

Our process permits the preservation of the functional and structural integrities of the targets/antigens. This has a significantly positive result on the quality of the protein and on the success of the proteomics and drug discovery applications.

Better Discovery

Uncover reliable and efficient drugs and antibodies as they are not locked in any particular conformation.

Made for PHARMA/Biotech
