Description

AA Sequence of recombinant protein: MREGPELSPD DPAGLLDLRQ GMFAQLVAQN VLLIDGPLSW YSDPGLAGVS LTGGLSYKED TKELVVAKAG VYYVFFQLEL RRVVAGEGSG SVSLALHLQP LRSAAGAAAL ALTVDLPPAS SEARNSAFGF QGRLLHLSAG QRLGVHLHTE ARARHAWQLT QGATVLGLFR VTPEIPAGLP SPRSE. Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Human 4-1BB Ligand. Anti-Human 4-1BB Ligand-specific antibody was purified by affinity chromatography and then biotinylated. Sandwich ELISA: To detect h4-1BBL by sandwich ELISA (using 100 μL/well antibody solution) a concentration of 0.25-1.0 μg/mL of this antibody is required. This biotinylated polyclonal antibody, in conjunction with PeproTech Polyclonal Anti-Human 4-1BBL (500-P169) as a capture antibody, allows the detection of at least 0.2-0.4 ng/well of Recombinant h4-1BBL. Western Blot: To detect h4-1BBL by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 μg/mL. Used in conjunction with compatible secondary reagents the detection limit for Recombinant h4-1BBL is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions. 500-P169BT-1MG will be provided as 2 x 500 μg

CD137 ligand (CD137L) is a type II membrane protein and part of the TNF superfamily. CD137L is a co-stimulatory molecule that is expressed on antigen presenting cells (DCs, monocytes/macrophages, B cells) and is upregulated upon activation. Its receptor, CD137/4-1BB, is found on a variety of cells, including inflamed endothelial cells, where its expression enhances extravasation of CD137L expressing monocytes. Activated T cells also express CD137, and engagement with CD137L enhances T cell proliferation, IL-2 secretion, survival, and cytotoxic activity. CD137L is also expressed on a majority of B-cell lymphomas, including mantle cell lymphoma, follicular lymphoma, and diffuse large B-cell lymphoma (but it is lacking on Hodgkin lymphoma and T-cell lymphoma). CD137L is also expressed in carcinoma cell lines, and is thought to be involved in T cell-tumor cell interactions.
