STORAGE:  2-8 C in the dark.

IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Interleukin-1 alpha (IL-1α or IL1A), also known as hematopoietin-1, is a protein of the interleukin 1 family. In general, Interleukin 1 is responsible for the production of inflammation, as well as the promotion of fever and sepsis. IL-1α inhibitors are being developed to interrupt those processes and treat diseases. IL-1 alpha is produced mainly by activated macrophages, as well as neutrophils, epithelial cells, and endothelial cells. It possesses metabolic, physiological, hematopoietic activities, and plays one of the central roles in the regulation of the immune responses. It binds to the interleukin-1 receptor. It is on the pathway that activates tumor necrosis factor-alpha. Shortly after an onset of an infection into organism, IL-1α activates a set of immune system response processes. In particular, IL-1α:  stimulates fibroblasts proliferation, induces synthesis of proteases, subsequent muscle proteolysis, release of all types of amino acids in blood and stimulates acute-phase proteins synthesis,  changes the metallic ion content of blood plasma by increasing copper and decreasing zinc and iron concentration in blood,    increases blood neutrophils, activates lymphocyte proliferation and induces fever.
