We practice a sole & custom-made approach to give you the edge

CALIXAR’s CALXGLUK is a very gentle detergent used to stabilize native membrane proteins. CALXGLUK is non-ionic and hence is not sensitive to ionic strength or pH fluctuations is well adapted to stabilize many different specific membrane proteins.

Calixar’s CALXGLUK can help deliver lipid detergent mixed micelles and protein detergent micelles. CALXGLUK also provides for the stabilization of native and functional membrane proteins within a solution.

Our CALXGLUK is provided in a powder form and is used in an aqueous solution or buffer which can also be mixed within biological substances (biological membranes).

CALXGLUK is a non-ionic calixarene based detergent / surfactant with three polar glucose groups and a heptyl chain.

CALIXAR’s CALXGLUK is non-ionic and therefore is not sensitive to ionic strength or pH variations and is able to stabilize specific membrane proteins. Due to the fluorinated chain, CALXGLUK does not solubilize lipid membranes.

CALIXAR’s CALXGLUK is a high-quality detergent / reagent utilized for research, drug discovery projects, and structural studies. Our technology is adapted for use in pharmaceutical and biotechnology companies, as well as for life science ​academic teams (biochemists, structural biologists, pharmacologists, virologists).
