About Us

RCMG Inc. is a technology-based company and we KNOW HOW to detect “differences” specific to disease conditions suitable for the diversity of personalized medicine.


RCMG Inc. was founded by Dr. Narimatsu*, a pioneer of establishing various technologies of glycoscience research over 35-years with great success, intellectual properties and know-how. Dr. Angata*, co-founder and CEO of RCMG Inc, has research experience in glycobiology over 25-years.
RCMG’s proprietary technology platform is able to continually create novel biomarkers/in vitro diagnostics (IVDs) to detect specific disease conditions suitable for the diversity of personalized medicine.

Aim of RCMG Inc. is to contribute to human health care by using glycotechnology that we studied and developed. Glycan is the fourth life chain in the biology field, which is our target molecule presenting differences in cells, organs, and individuals.
Current IVD pipeline includes inflammation, infectious disease, and oncology. Since glycosylation of cellular surfaces and secreted proteins reflects conditions of cells in patients, suffering from infections or cancers, glyco-biomarkers for specific diseases would create more accurate biomarkers.

RCMG’s pharmaco-glycoproteomics is able to stratify individual samples in view of drug response. Pharmaco-glycoproteomics would contribute to obtain early signal efficacy of new drug in the development, stratify patient subpopulation and determine effective inclusion/exclusion criteria prior to large clinical trial for pharmaceutical companies.

Development of novel glycobiomarker/IVD.

Dr. Hisashi Narimatsu, MD and Ph.D. (Chair of the board)

Dr. Narimatsu graduated from the School of Medicine and Graduate School of Medicine at Keio University where he received his MD and PhD, respectively. At U.S. National Institutes of Health (NIH), he successfully cloned the first glycosyltransferase, b1,4galactosyltransferase. After he joined AIST and led 10 national projects for the development and application of glycotechnologies, dedicating to facilitate the glycoscience.
