The present invention discloses a new gene, termed PSMA-like, that is very similar to the prostate-specific membrane antigen gene and cross-reacts with current detection methods for PSMA. The present invention relates to a nonaqueous electrolytic solution prepared by dissolving an electrolyte salt in a nonaqueous solvent, which comprises a sulfonic ester compound represented by the following Formula in an amount of 0. The rubber loop is partially cured and is then adhered to the inner wall of the aft end of the rocket motor case by using a silicone rubber loop of the apparatus. Bicomponent fibers having a common core polymer and different sheath polymers can be extruded from alternate spinneret orifices in the same die plate. The marker is an ester derivative of fluorescent material, and the silent marker may be detected by measuring the fluorescence generated from the selective hydrolysis of the ester moiety under enzymatic action. The photostimulated luminescent light emitted by irradiation of excitation light is detected by the two line detection sections.
