Unlock the Untapped Frontier of GPCR Drug Discovery
Tanso Biosciences unlocks the whole GPCR universe with a proprietary assay platform, enabling pharma and biotech to de-risk drug discovery, expand pipelines, and accelerate first-in-class medicines.
Tanso Biosciences is a leading innovator in GPCR functional assays, providing a comprehensive platform to evaluate receptor activity across 550 validated human and mouse targets. Our ultra-sensitive and versatile technology covers all major G protein subtypes—including challenging pathways like G12/13—and supports rapid, customizable screening and detailed pharmacological analysis. Serving pharmaceutical, biotech, food industries, and academia worldwide, we accelerate discovery through reliable assays, orphan GPCR de-orphanization, and cross-species comparisons, backed by international patents and scientific validation.
Partner with us to unlock new therapeutic frontiers.
Why Tanso Bio?
At Tanso Biosciences, we believe drug discovery deserves better tools—tools designed not just for what’s easy, but for what’s possible. Our proprietary GPCR functional assay platform breaks through the traditional barriers that have limited exploration of this vital receptor family. We don’t just offer assays—we open new therapeutic frontiers.
What Sets Us Apart
- Unmatched GPCR Coverage, Detected with Precision
Profile 550 validated GPCRs — 300 human and 250 mouse — across all four major G protein families, including G12/13, long considered difficult to assay. Our proprietary platform detects GPCR-induced intracellular signaling with high sensitivity and low background noise, making it reliable even for orphan GPCRs and subtle biological effects that conventional assays miss. - Fast, Flexible, and Client-Centric
We adapt our assay designs to fit your specific needs—whether you need rapid turnaround screening, detailed SAR analysis, or custom cross-species profiling. - Scientifically Validated, Globally Protected
Our technology is protected under international patents (WO/2020/026979) and has been validated through its use in academic and industry research programs.
