Products from KACTUS Biosystems
KACTUS is your centralized source for quality recombinant proteins and enzymes. Founded in March 2018, the KACTUS protein engineering team achieved a remarkable breakthrough just a few months later when it became the first company to successfully express the complex multi-transmembrane protein Claudin 18.2. Shortly thereafter, KACTUS developed its breakthrough protein technology platform SAMS™ (Structure-Aided Multiplex Screening), which enables high activity and purity of difficult-to-express targets. Today, KACTUS' first-class products facilitate novel drug development, including in the fields of immunotherapy, gene editing and mRNA therapeutics.
