Abstract
The present invention relates to an amphiphilic polymer which includes a large amount of hydrophilic structures and hydrophobic structures, and thereby effectively stabilizing a membrane protein having a hydrophobic surface in an aqueous solution. A method of preparing an amphiphilic polymer represented by Formula 1 includes reacting a poly-gamma-glutamic acid with a reaction product of a fluorescent dye, biotin, an alkyl carboxylic acid having 1 to 10 carbon atoms or a cycloalkyl carboxylic acid having 5 to 20 carbon atoms having a carboxyl group, and dicyclo-hexylcarbodiimide (DCC) and reacting the poly-gamma-glutamic acid with DCC after reacting the poly-gamma-glutamic acid with the reaction product, and reacting the poly-gamma-glutamic acid with a hydrophilic amine and a hydrophobic amine.
