What makes us special

We use a unique & custom-produced program to provide you with an edge

CALIXAR’s FLAC6 is manufactured into a powder form and is used in an aqueous solution or buffer. FLAC6 can be combined with biological substances (biological membranes).

Our clients are able to use FLAC6 to produce lipid detergents, mixed micelles, and protein detergent micelles. FLAC6 empowers clients to extract, to solubilize and to stabilize native and functional membrane proteins in a solution.

FLAC6 is a very gentle non-ionic detergent to extract, solubilize and to stabilize native membrane proteins. As it is indifferent to ionic strength or pH variations it is ideal to extract, solubilize and stabilize particular membrane proteins of high medical relevance.

Proprietary mild detergent

CALIXAR’s FLAC6 is non-ionic and therefore is not sensitive to ionic strength or pH variations. It is well conformed to extract, to solubilize and to stabilize specific membrane proteins.

Specifically made for Biotech

CALIXAR’s FLAC6 extracts high-quality membrane proteins used for research, pharmaceutical discovery, and structural studies. FLAC6 is designed for pharmaceutical and biotechnology companies, as-well-as for academic teams (biochemists, structural biologists, pharmacologists, virologists) that are involved in the life science fields.
