Abstract
A polypeptide porous body of the present invention is a porous body of a polypeptide derived from spider silk proteins. The polypeptide includes a water-insoluble polypeptide. The polypeptide porous body has an apparent density of 0.1 g/cm3 or less. A method for producing the polypeptide porous body includes: a solution production step in which the polypeptide is dissolved in at least one solvent selected from DMSO, DMF, and these with an inorganic salt, so as to obtain a solution of the polypeptide; a step in which the solution produced in the solution production step is substituted with a water-soluble solvent so as to obtain a polypeptide gel; and a step in which the polypeptide gel is dried. Thereby, the present invention provides a polypeptide porous body having excellent water absorbability and a polypeptide porous body suitable for application to a living body, and a method for producing the same.
