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.

CCL11, or C-C motif chemokine 11, also known as eosinophil chemotactic protein and eotaxin-1, is a small cytokine belonging to the CC chemokine family. CCL11 selectively recruits eosinophils by inducing their chemotaxis, and therefore, is implicated in allergic responses. Chemokine receptors for which CCL11 is a ligand include CCR2, CCR3 and CCR5. However, it has been found that eotaxin-1 (CCL11) has high degree selectivity for its receptor, such that they are inactive on neutrophils and monocytes, which do not express CCR3. Increased CCL11 levels in blood plasma are associated with aging in mice and humans. Additionally, it has been demonstrated that exposing young mice to CCL11 or the blood plasma of older mice decreases their neurogenesis and cognitive performance on behavioral tasks thought to be dependent on neurogenesis in the hippocampus. Higher plasma concentrations of CCL11 have been found in current cannabis users compared to past users and those who had never used. CCL11 has also been found in higher concentrations in people suffering from schizophrenia; cannabis is a known trigger of schizophrenia.
