Yeastern Biotech

What Yeastern Biotech does

Yeastern Biotech (益生生技) is a Taiwan-based molecular biology reagent manufacturer founded in 2000 and headquartered in New Taipei City, operating with approximately 11 employees. The company supplies research institutions, academic laboratories, and biotechnology and pharmaceutical firms with a catalog of branded reagents for cloning, protein expression, PCR/RT-PCR, nucleic acid extraction, and gel staining. Its flagship product line, ECOS™ competent cells, is engineered to deliver E. coli transformations in roughly six minutes, a workflow speed advantage over conventional 30-minute protocols. The YLEX yeast expression kit is built on a licensed Yarrowia lipolytica platform, a non-conventional yeast suited to industrial-scale fermentation and difficult-to-express proteins, distinguishing the catalog from generic Saccharomyces-based kits.

The company also offers the T&A™ cloning kit with five-minute ligation, the Deoxy+ RT-PCR kit line, the EZtime Real-Time PCR premix, the HiYield/Genomic/UniversAll™ DNA and RNA extraction kits, the EtB"Out" safer nucleic acid stain as an ethidium bromide alternative, and OEM manufacturing services for third-party reagent brands. Through its subsidiary GeneOne Diagnostics, the group has extended into human infectious-disease diagnostics, notably COVID-19 test kits, and has more recently launched the ASF UniOn kit for African Swine Fever detection, opening an animal-health diagnostics vertical.

Yeastern's commercial model combines direct sales to academic and biotech customers with global distribution through authorized resellers, exemplified by the February 2026 appointment of Major Science as an authorized global reseller for ECOS™ competent cells. The company is privately held, has no listed equity instrument, and has not disclosed revenue, headcount growth, or capital raise history; the business is supported by a long-tail catalog with multi-vertical exposure across life-science research, animal health, and agricultural testing, including a 2025 partnership with ACCUSENS BIOMED to apply molecular diagnostics for banana pathogen testing in Southeast Asia.
