Weitere Details:: TNFSF9, a type II transmembrane glycoprotein and member of the TNF superfamily, preferentially expressed by B cells, which acts as a ligand for CD137 (4-1BB ligand receptor/TNFRSF9). Interaction between 4-1BBL and its receptor acts as a co-stimulatory signal for T cell activation and expansion, and is involved in the generation of cytotoxic T cells (Tc) and in the process of antigen presentation. Expression of 4-1BBL by a variety of carcinoma cells, suggests a role for 4-1BBL in tumor cell-T cell interactions. Applications: Suitable for use in Flow Cytometry and Western Blot. Other applications not tested. Recommended Dilution: Flow Cytometry: 1:50-1:200 Western Blot: 1:500-1:1000 Optimal dilutions to be determined by the researcher.
