Abstract of the Disclosure A filler for use in chromatography comprises porous spherical grains of poly(.alpha.-amino acid). The spherical grains can be produced by a method which comprises the steps of preparing a solution of hydrophobic poly(.alpha.-amino acid) such as poly n-leucine dissolved in an organic solvent containing an additive; adding the solution to an aqueous medium and agitating the medium so as to obtain a dispersion of the spherical grains of the poly(.alpha.-amino acid) dispersed in the aqueous medium while evaporating the organic solvent; taking out the spherical grains of polyamino acid from the disper- sion and removing the additive from the grains. The additive is noncompatible with the organic solvent in which the poly (.alpha.-amino acid) is dissolved, and has a higher boiling point than those of the organic solvent and the aqueous medium.
