CALIXAR is the first to produce native, wild-type, unmutated and untruncated targets.

Better discovery

Develop reliable and effective drugs and antibodies as they are not locked in any specific conformation.

Why choose us?

We use a unique & tailor-made procedure to give us the edge

CALIXAR’s DDTAC is a very mild detergent used to extract native membrane proteins. DDTAC can solubilize and stabilize more efficiently fragile membrane proteins of high medical relevance.

Our DDTAC is non-ionic and therefore not sensitive to ionic strengths or pH variations and can be customized to solubilize and stabilize specific membrane proteins.

DDTAC helps our clients to produce lipid detergents, mixed micelles and or protein detergent micelles. CALIXAR allows biochemists, structural biologists, pharmacologists and or virologists to work with high-quality DDTAC to extract, solubilize and stabilize native and functional membrane proteins in the solution for research purposes, drug discovery and or target validation.

CALIXAR’s DDTAC is non-ionic and therefore is not sensitive to ionic strength or pH variations and is a very powerful way to extract, solubilize and stabilize particular membrane proteins.

CALIXAR’s DDTAC extracts high-quality membrane proteins that are used in research, drug discovery projects and structural studies. Our DDTAC  is used by pharmaceutical and biotechnology companies, as well as life science academic teams (biochemists, structural biologists, pharmacologists, virologists).
