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.

Description:

Chemokine (C-C motif) ligand 24 (CCL24), also known as Myeloid Progenitor Inhibitory factor 2 (MPIF-2) or eosinophil chemotactic protein 2 (Eotaxin-2) and small inducible cytokine A2 (SYCA2), is a small cytokine belonging to the CC chemokine family. CCL24 interacts with chemokine receptor CCR3 to induce chemotaxis in eosinophils. This chemokine is strongly chemotactic for resting T lymphocytes and slightly chemotactic for neutrophils. Elevated levels of Eotaxin-2 have been seen in patients with aspirin-exacerbated respiratory disease such as asthma. People with lower plasma levels of Eotaxin-2 have not been showing tendency to develop aspirin inducible asthma.
