The Kazusa Metabolomics Portal

Metabolomics is analytical technologies to quantitatively detect as many as small molecules (metabolites) in organisms. Komics (Kazusa Metabolomics Database) is a web portal to the databases, tools and other information that were developed and produced through the metabolomics studies of the Shibata's Laboratory in Kazusa DNA Research Institute.

Most of the products were developed in the research project named "Development of Fundamental Technologies for Controlling the Material Production Process of Plants" (PMPj) supported by New Energy and Industrial Technlogy Development Organization (NEDO, Japan).

MassChroViewer updated


MassChroViewer tool - a raw chromatogram data viewer for data quality checking - is updated to version 1.6.1. A function to save and reconstruct analyzing condition was added. The export function for MSn spectra was improved too.


Food Metabolome Repository is now on public

Food Metabolome Repository

Food Metabolome Repository, which contains information of all peaks including unknowns obtained from more than 100 Japanese foods using LC-MS, is now available. The specificity of samples for an unknown compound of your interest may help further annotation and identification of the compound.


FlavonoidSearch released


FlavonoidSearch—a system for high-accuracy prediction of flavonoid aglycones using MS/MS spectra— is released.
