| Outline of Final Research Achievements |
Detergents are used to lyse cells, solubilize proteins, and prevent nonspecific binding in purification steps. They are essential in particular, for purification and characterization of integral membrane proteins. However, many of them affect the native structure of protein and result to lose the protein function. For that reason, increasing efforts for developing a new type of detergent which gentler solubilizing agents without interfering with membrane protein structure and activity. In order to develop of new detergents, we synthesized alkyl glycoside derivatives having monosaccharide structure (glucose, mannose, galactose, and allose residue), fluorinated glucose derivatives and branched trimannoside derivative. Using these alkyl glycoside derivatives, we characterized their physico-chemical properties such as critical micelle concentration by fluorescent dye method and isothermal titration calorimetry, and solubilization behavior of proteins from membranous fraction of ER.
