LentiBOOST® is a highly effective, non-cytotoxic transduction enhancer for preclinical and clinical application of lentiviral vectors. It is a universal polaxamer-based, receptor-independent adjuvant which facilitates fusion of lenitivrus particles with cell membrane, significantly increasing transduction efficiency. LentiBOOST® can be applied to a wide range of clinically relevant cell types including CD34+ hematopoietic stem cells (HSCs), primary T cells, NK cells, fibroblasts, and hard-to-transduce murine T cells. These unique features make it a promising candidate to improve clinical transduction protocols for ex vivo gene therapies and CAR-T cell therapies. In the demonstration above, LentiBOOST™ increases transduction by a factor of 5.
