4-1BB (CD137) Fc Chimera, Human

Measured by its binding ability in a ligand-receptor binding ELISA. When recombinant human 4-1BB Fc Chimera is Immobilized at 1 µg/mL (100 µL/well), the concentration of recombinant human 4-1BB Ligand that produces 50% optimal binding response is found to be approximately 5-15 ng/mL.

4-1BB (CD137) Fc Chimera, Human

4-1BB(CD137) is a member of the tumor necrosis factor (TNF) receptor family. Mature human 4-1BB consists of a 163 amino acid extracellular domain (ECD) with four TNFR cysteine‑rich repeats, a 27 aa transmembrane segment, and a 42 aa cytoplasmic domain; 4-1BB (CD137) is expressed as a disulfide-linked homodimer on various populations of activated T cell including CD4+, CD8+, memory CD8+, NKT, and regulatory T cells as well as on myeloid and mast cell progenitors, dendritic cells, mast cells, and bacterially infected osteoblasts. It binds with high affinity to the transmembrane 4-1BB Ligand/TNFSF9 which is expressed on antigen presenting cells and myeloid progenitor cells. This interaction co stimulates the proliferation, activation, and/or survival of the 4-1BB expressing cell. It can also enhance the activation-induced cell death of repetitively stimulated T cells.
