Recombinant human CXCL8 is expressed in E. coli, refolded and purified to yield the mature form of protein that is secreted from cells after cleavage of the signal peptide. Human CXCL8 is a 77 amino acid protein that is the prototypical CXC chemokine which is expressed by fibroblasts and keratinocytes. Also known as Interleukin 8, this chemokine binds and activates two G protein-coupled receptors, CXCR1/CXCR2 on a variety of cells such as neutrophils, T-cells, endothelial cells, macrophages and keratinocytes. CXCL8 is N-terminally processed to yield the major in vivo species, the 6-77 variant. (link to CXCL8 6-77 product page)
