Biochem/physiol Actions

Interleukin-8 (IL-8) chemoattracts and activates neutrophils. It is involved in guiding neutrophils and oligodendrocytes to sites of infection. The protein also stimulates angiogenesis and tumor growth. It is also associated with inflammatory diseases.

General description

Interleukin-8 (IL-8) is a proinflammatory CXC chemokine that can signal through the C-X-C motif chemokine receptors 1 and 2 (CXCR1 and 2). It is also called as C-X-C motif chemokine ligand 8 (CXCL8). IL-8 is secreted by monocytes and endothelial cells. The gene encoding Il-8 is localized on human chromosome 4q13.3. Recombinant human IL-8 (monocyte-derived) is an 8.4kDa protein containing 72 amino acid residues.

Physical form

Lyophilized with no additives.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
