Yeasen Biotechnology Verified partner
Yeasen Biotechnology is a life-science reagent company founded in 2014, built around proprietary enzyme-evolution (directed-evolution) technology for developing high-performance enzymes and biological reagents.
More detail +
Its catalog spans four areas: molecular biology reagents (qPCR/RT-qPCR, reverse transcription, high-fidelity PCR, and cloning), next-generation sequencing library preparation (DNA, RNA, single-cell, and epigenetics), molecular diagnostics enzymes and master mixes, and biopharma raw materials for mRNA, viral-vector, and cell-therapy manufacturing.
A key strength is its enzyme-engineering platform, which produces optimized polymerases, reverse transcriptases, ligases, and nucleases, including GMP-grade materials and a transfection reagent for AAV production with an FDA Drug Master File on file.
Yeasen also provides recombinant proteins, cytokines (including GMP-grade), transfection reagents, and cell-biology tools, serving academic, diagnostic, and biopharmaceutical customers. All Yeasen products are for research use only.
