Core Technologies

We regard detection platform such as immunochromatography, antibody generation technology, and high-sensitivity detection technology, as our core technologies. Through the fusion and development of these technologies, we are working on research and development to create original diagnostic reagents. We consistently strive to develop new diagnostic fields and innovate in testing and inspection technologies by improving our core technologies and integrating new findings.

Detection Platform

Utilizing the knowledge and experience we have accumulated over decades in immunochromatography, we are proceeding with research and development on a new detection platform with the advantages of rapidity and simplicity. To meet medical needs, we are also developing a detection system that combines specialized measuring equipment.

Principle of Immunochromatography

Antibody Generation Technology

We have established a technology for generating mouse monoclonal antibodies to obtain high-quality antibodies by selecting antigens for immunization and optimizing the immunization methods. We are also developing a method for producing antibodies artificially by obtaining antibody genes from antibody-producing cells.

High-Sensitivity Detection Technology

Our patented platinum-gold colloid technology enables high-sensitivity immunochromatography. We are also developing a fluorescence labeled immunochromatography that uses a long-lived fluorescent substance. At the same time, we are working on a collaborative R&D to develop optical measurement devices for the detection of fluorescence. To increase the detection sensitivity, we need to not only develop labeling substances, but also improve the performance of antibodies used. Furthermore, by applying a new optical detection device, we are developing a detection method with higher detection sensitivity. By combining our core technologies, we have achieved high sensitivity detection.

Platinum-Gold Colloid Technology

Instead of the gold colloid (red color) used in conventional immunochromatography, we have developed our proprietary black “platinum-gold colloid” with high-visibility and applied it to our products “ImunoAce/Capilia series.” It is also known affectionately as the “black line.” A black platinum colloid is applied to the surface of a gold colloid to create a labeling substance with improved visibility and characteristics of gold colloid, which goes well with an antibody as a labeling substance for immunochromatography.

Black Line

Test and control lines are displayed in highly visible black lines using our proprietary nanotechnology “platinum-gold colloid” (patented technology).
