特徴

• IL-8 is a chemotactic factor that attracts neutrophils, basophils, and T-cells, but not monocytes. It is also involved in neutrophil activation. It is released from several cell types in response to an inflammatory stimulus. IL-8(6-77) has a 5-10-fold higher activity on neutrophil activation, IL-8(5-77) has increased activity on neutrophil activation and IL-8(7-77) has a higher affinity to receptors CXCR1 and CXCR2 as compared to IL-8(1-77), respectively. {ECO:0000269|PubMed:11978786, ECO:0000269|PubMed:2145175, ECO:0000269|PubMed:2212672}.
• Biological Activity:Fully biologically active when compared to standard. The ED50 as determined by a chemotaxis bioassay using human CXCR2 transfected mouse BaF3 cells is less than 2ng/ml, corresponding to a specific activity of ＞ 5.0 ×10e5 IU/mg.
