Atract™ Kits


The Atract™ Kit product family contains two versions of biocompatible composites of irreversibly bound antibodies, designed to activate and expand human T-cells. Each offers specific advantages that can fulfill different customer needs. The Atract™ Kit V1 is designed for optimal activation, providing a unique opportunity to fine-tune activity by adjusting the CD3 to CD28 bead ratio, whereas the Atract™ Kit V2 is optimized for superior proliferation and user-friendly operation. 

The Atract™ Kit reagents align with our slogan, "No magnets, no residual antibodies, just pure cells," and cannot be phagocytized. The reagents are compatible with conventional culture flasks, bags, and plates.
