4-1BB/TNFRSF9, Human (HEK293, Fc)

4-1BB/TNFRSF9 Protein, Human (HEK293, Fc), a recombinant human 4-1BB/TNFRSF9 Protein produced in HEK293 cells, has an Fc fragment at the C-terminus. Recombinant Human 4-1BBRTNFRSF9, an inducible T cell molecule belonging to the TNF receptor superfamily, could promote the expansion of antigen-specific T cells and prevent activation-induced death of CD8+ T cells[1].
