Cytofinity™-SP: PEG-free LNP optimized for spleen and immune cell targeting

Many genetic therapies require efficient delivery to immune cells, but conventional lipid nanoparticles (LNPs) primarily accumulate in the liver, limiting their effectiveness for immune-focused applications. Cytofinity™-SP is a PEG-free LNP formulation engineered to detarget the liver while achieving high spleen tropism and enhanced delivery to immune cells. By enabling more targeted delivery to the immune system, Cytofinity™-SP is designed to support next-generation therapeutic approaches, including in vivo CAR, in vivo gene editing, and immunotherapy.

Target Tissues:

  • Spleen
