Yeastern Biotech

Yeastern Biotech is a Taiwan-based private biotechnology company focused on life science research tools, molecular biology reagents, and selected diagnostic products. Its core business centers on commercially marketed products such as chemically competent cells, cloning vectors, protein expression systems, PCR/qPCR/RT-PCR reagents, and DNA/RNA extraction kits. The company highlights its ECOS competent cells as a flagship product line and also offers OEM and ODM services for research-use and biomedical customers. Yeastern Biotech appears to operate as a commercial life science tools supplier rather than a therapeutics developer, with capabilities spanning reagent development, assay-related products, and manufacturing under quality systems including ISO 13485 and GMP.
