Reconstitution Reconstitute the lyophilized recombinant Porcine Interleukin-1 beta (rPoIL-1β) to 100 μg/mL using ddH2O or PBS. Storage & Stability Lyophilized recombinant Porcine Interleukin-1 beta (rPoIL-1β) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week 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 Interleukin-1 beta (IL-1 β) is one of the major inflammatory cytokines found in atherosclerotic lesions[1]. Interleukin-1β (IL-1β) acts throughout the IL-1β system, which contains IL-1β and the IL-1β receptor (IL-1R), accessory protein (IL-1RacP), and receptor antagonist (IL-1Ra). In pigs, the expression of the members of the IL-1β system was documented in uterine tissues during the oestrous cycle and early pregnancy, as well as in embryos harvested during the peri-implantation period[2]. Interleukin-1 beta regulates cell proliferation and activity of extracellular matrix remodelling enzymes in cultured primary pig heart cells[3]. |
