Method for producing amino acid crystals and method for producing protein crystals

Abstract

The object of the present invention is to provide a new application of an optical vortex. For the object, a method for producing crystalline amino acid comprises a step of irradiating a saturated solution of amino acid with optical vortex, and depositing crystalline amino acid in the saturated solution of amino acid. In the method, it is desirable that the amino acid contains at least one of alanine, arginine, asparagine, asparagine acid, cysteine, glutamine, glutamine acid, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine, and derivative of them.
