The present invention provides a circular polarization illumination device which can irradiate right-circularly polarized light at a large light amount from a light source of right-circularly polarized light with a high efficiency and can irradiate left-circularly polarized light at a large light amount from a light source of left-circularly polarized light with a high efficiency, and a plant growth regulation method that can efficiently regulate the promotion or inhibition of the growth of plants by using the circular polarization illumination device. Moreover, the illumination device includes a light-emitting light source, a reflective polarizing plate, reirradiation unit, and circular polarization conversion unit.

Circular polarization illumination device and plant growth regulation method

A carrier comprises a base plate, a polymeric film, which has been bound on a surface of the base plate, and a ligand, which has been bound with the polymeric film. The ligand has been bound with the polymeric film at a density falling within the range of 1.0&#xd7;10pieces/mmto 3.3&#xd7;10pieces/mm. The carrier is produced with a process, comprising the steps of: causing the polymeric film to bind on the base plate, and causing the ligand to bind with the polymeric film, the step of causing the ligand to bind with the polymeric film being performed in an organic solvent.

A method for purifying bioactive substances includes the steps of: causing a bioactive substance having histidine units to contact media, each constituted by a substrate, ligands which are physically attached to the surface of the substrate, and Cu(II) or Fe(II) metal ions which are covalently bonded to the ligands; causing the bioactive substance to covalently bond with the metal ions via the histidine units; and washing the media with an amount of 1 nmol/L to 10 mmol/L imidazole derivative solution 60 times the volume of the media or greater. In the case that the metal ions are Cu(II), the bioactive substance which has covalently bonded with the Cu(II) via the histidine units are recovered by one of a 10 mmol/L to 1 mol/L imidazole derivative solution and a 0.5 mmol/L to 5 mol/L EDTA solution.
