KACTUS

At KACTUS, we specialize in high-activity recombinant proteins and enzymes to accelerate drug and therapeutic development. Our 3,000+ product catalog covers a variety of protein, species, tags, and labels. These rigorously tested products can be applied to a variety of research and drug development areas including antibody drug discovery, cell therapy, gene therapy, and mRNA therapeutics. Each product undergoes strict quality control for purity, performance, consistency, and stability of supply. We’ve developed an expertise in difficult-to-express proteins, including being the first to recombinantly produce full-length Claudin 18.2 protein. Since then, we’ve developed a large catalog of multipass transmembrane proteins, MHC complexes, and other challenging proteins and enzymes. Researchers also value our custom protein expression services, owing to our demonstrated expertise in complex protein expression and responsive support.
