Abstract: An object of the present invention is to provide a cytotoxic assay using a new established fish cell line. The invention attained according to the object is a cytotoxic assay, wherein an evaluation of toxicity of a specimen is performed on the basis of its toxicity to an established cell line originated from sturgeon, preferably a STIP-1 cell line (FERM BP-8421) and a STIP-3 cell line (FERM BP-8422). Furthermore, another object of the present invention is to provide a new established cell line expected to be used in the diagnosis of viral infection disease of sturgeon and so on. The invention attained according to the object is an established cell line originated from a sturgeon eyeball, particularly a STIP-1 cell line (FERM BP-8421) and a STIP-3 cell line (FERM BP-8422).

Abstract: A method for manufacturing optical elements, having the following steps: preparing a plural number of glass planar plates, each of the planar plates having a light-separating coating on one surface; laminating the planar plates and boding the planar plates together by a translucent first adhesive so as to make a laminate; cutting the laminate in a first direction inclining at a specified angle at a specified pitch so as to make a plural number of laminate divisions; polishing both cut surfaces of each of the laminate divisions; stacking the laminate divisions such that the polished surfaces face each other and temporarily bonding the stacked laminate divisions together by a second adhesive; cutting the temporarily bonded stack of laminate divisions in a second direction perpendicular to surfaces of the stack so as to make a plural number of temporarily bonded plates; polishing both surfaces of each of the temporarily bonded plates; removing the second adhesive so as to make a plural number of long chains of o
