Recombinant Human 4-1BB Ligand/TNFSF9 (Human 4-1BBL/TNFSF9) _ C230284 Size:100 μg The biological activity determined by4 1BBL, a member of the TNF superfamily, is expressed in B cells, dendritic cells, activated T cells and macrophages. 4 1BBL binds to its receptor 4 1BB, and provides a co stimulatory signal for T cell activation and expansion. The human 4 1BBL gene codes for a 254 amino acid type II transmembrane containing a 28 amino acid cytoplasmic domain, a 21 amino acid transmembrane protein domain, and a 205 amino acid extracellular domain.
