KACTUS - Your Centralized Supplier for Quality Recombinant Proteins

KACTUS specializes in design and manufacturing of high-purity, high-activity, recombinant protein and enzyme products for a range of fields including antibody drug discovery, immunotherapy, gene therapy, and mRNA therapeutics. Our catalog selection of 2500+ ready-made recombinant proteins includes various targets, species, tags, and labels. We carefully select our catalog products based on the unmet needs of scientists in drug development. Approval of each protein is based on product quality and reliability of supply.

SAMS™ Protein Engineering Platform

Each protein is developed using our proprietary protein engineering platform, Structure-Assisted Multiplex Screening (SAMS™). Individual protein structures are optimized using advanced bioinformatics, structural analysis, and 3D modeling. Multiple protein constructs are tested in various expression conditions to optimize activity, yield, and configuration. Demonstrating the strength of our protein engineering platform, KACTUS was the first company to recombinantly express the multi-transmembrane protein Claudin 18.2. Since then we’ve added additional difficult-to-express antibody drug targets such as CCR8 and CD24.
