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 8 (IL-8) or CXCL8 is a member of the CXC chemokine family and is produced by macrophages and other cell types such as epithelial cells, airway smooth muscle cells and endothelial cells. It induces chemotaxis in target cells, primarily neutrophils but also other granulocytes, causing them to migrate toward the site of infection. IL-8 also induces phagocytosis once they have arrived. IL-8 is also known to be a potent promoter of angiogenesis. Interleukin-8 is a key mediator associated with inflammation where it plays a key role in neutrophil recruitment and neutrophil degranulation. As an example, it has been cited as a pro-inflammatory mediator in gingivitis and psoriasis. Interleukin-8 secretion is increased by oxidant stress, which thereby cause the recruitment of inflammatory cells and induces a further increase in oxidant stress mediators, making it a key parameter in localized inflammation. IL-8 has also been implied to have a role in colorectal cancer by acting as an autocrine growth factor for colon carcinoma cell lines. If a pregnant mother has high levels of interleukin-8, there is an increased risk of schizophrenia in her offspring. High levels of Interleukin 8 have been shown to reduce the likelihood of positive responses to antipsychotic medication in schizophrenia.  IL-8 has also been implicated in the pathology of cystic fibrosis. Through its action as a signaling molecule IL-8 is capable of recruiting and guiding neutrophils to the lung epithelium.
