Reconstitution Reconstitute the lyophilized recombinant Human Activation-inducible TNF-related Ligand/AITRL (rHuActivation-inducible TNF-related Ligand/AITRL) to 100 μg/mL using ddH2O. Storage & Stability Lyophilized recombinant Human Activation-inducible TNF-related Ligand/AITRL (rHuActivation-inducible TNF-related Ligand/AITRL) is stored at -20°C. After reconstitution, it is stable at 4°C for 2 weeks or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Human activation-inducible tumor necrosis factor receptor (AITR) and its ligand, AITRL, are important costimulatory molecules in the pathogenesis of autoimmune diseases. AITR and AITRL are both costimulatory molecules, which are pairs of molecules that interact with each other and are expressed at high levels on the surface of CD4+ CD25+ T cells. When these costimulatory molecules are activated, they inhibit the ability of the CD4+ CD25+ T cells to suppress the autoreactive T-cells. This results in an increased autoimmune response[1]. |
