Our Background
From Pfizer to PathGene
PathGene's founder worked as a Quality Engineer at Pfizer, deeply involved in building one of the world's most stringent pharmaceutical manufacturing quality systems. That experience revealed a persistent gap: raw material suppliers rarely operated at the quality standards demanded by finished-goods pharmaceutical manufacturers.
In 2018, the founding team returned to Nanjing with a mission: bring Pfizer-level quality standards to the synthetic biology ingredient supply chain. We implemented cGMP manufacturing practices, established ISO 17025-accredited third-party testing protocols, and secured 12 invention patents on our core enzymatic synthesis processes.
Today, our products are used by pharmaceutical companies, nutraceutical brands, and research institutions across 50+ countries. But our founding goal has never changed: every batch, every COA must withstand scrutiny from the world's most regulated markets.

Mission & Values
Why We Never Compromise on Purity
In regulated markets, a 0.5% purity gap can mean an entire batch rejection. Our mission is to ensure no customer ever has to compromise on ingredient quality for any market.
🔬
Science First
Every process decision is driven by science, not cost-cutting.
📋
Full Traceability
From raw material to finished product, every step is documented and traceable.
🤝
Partner Mindset
We don't sell ingredients — we partner with you through product development.
🌍
Global Compliance
FDA, EMA, NMPA documentation support built into every engagement.

R&D Capability
300m² Advanced Bioengineering Lab
PathGene's R&D center is equipped with multiple Agilent HPLC systems, automated digital polarimeters, micro-spectrophotometers, and comprehensive strain construction and gene editing equipment for rapid metabolic pathway optimization.
A parallel bioreactor cluster (1L–50L) supports process model development, ensuring R&D results can be directly scaled to industrial production and significantly shortening the cycle from lab to ton-scale output.
AI Enzyme Engineering Platform
Leveraging AI algorithms for virtual screening of our proprietary sequence library, PathGene achieves rapid, precise identification of thermostable, alkaline-tolerant, and solvent-resistant enzymes — reducing R&D risk and enhancing chiral purity.
