Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against 20 mM HAc-NaAc, pH 5.0, 150 mM NaAc buffer. Endotoxin Level <1 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human Interleukin-6 (rHuIL-6) to 100 µg/mL using ddH2O. Storage & Stability Lyophilized recombinant Human Interleukin-6 (rHuIL-6) 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-6 (IL-6) is a 26-kD protein released by fibroblasts, T lymphocytes, endothelial cells, monocytes, and keratinocytes during inflammatory responses. IL-6 has pluripotent activities, including the stimulation of the monocytic lineage, the induction of megakaryopoiesis and the hepatic acute phase response, as well as the modulation of T- and B-cell responses. IL-6 is also capable of mediating direct and indirect tumor cell destruction and that it is potentially important for the immunotherapy of cancer[1. Recombinant human interleukin-6 (IL-6/BSF-2/HSF) regulates the synthesis of acute phase proteins in human hepatocytes[2]. |
