SAMS™ Protein Engineering PlatformEach 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.Custom Protein ExpressionWe know you are also familiar with how fast the drug development market changes.
