Mission/Background :
Researchers at the Faculty of Medicine, The University of Tokyo have developed an extraordinarily sensitive, comprehensive, and specific cell-based assay for GPCRs. Tanso Biosciences is the academic spin-off to apply their innovation and revolutionize drug discovery.

With its assay platform, Tanso Biosciences contributes to promoting human health by expanding frontiers, accelerating research, and reducing risks of drug development.

Our business model consists of two pillars.

1. Contract services
We provide exhaustive on-target and off-target screening services for pharmaceuticals and biotechs.

2. Drug discovery
We make best use of our reliable one-fits-all GPCR functional assay method and target GPCRs that have historically been difficult with existing methods, namely, orphan receptors, G12/13-coupled receptors, and Gi/o-coupled receptors.

Technology & Business
