Our Abpromise guarantee covers the use of ab18672 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ELISA Use at an assay dependent concentration.
Neutralising Use at an assay dependent concentration.

In chemotaxis assay, the antibody inhibited 95.1% of the chemotactic activity of IL-8 on RB/293 cell. 50ug/ml of antibody and 10ng/ml of human IL-8 were used in assay. This antibody inhibited the chemotactic effect of human IL-8, and had no inhibitory effect of MIP 1-beta and RANTES in neutrophil chemotaxis assay, indicating that the neutralizing activity is specific. The antibody also neutralized IL-8 induced calcium influx in human granulocytes.

WB Use a concentration of 0.02 - 0.1 µg/ml. Predicted molecular weight: 12 kDa.

Concentration of 0.02-0.1 ug/ml of ab18672 will allow visualization of 100 ng/lane of human IL-8

IHC-Fr 1/2000.
IHC-P 1/2000.
ICC/IF Use at an assay dependent concentration. PubMed: 18697197


  • Function
    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.
  • Sequence similarities
    Belongs to the intercrine alpha (chemokine CxC) family.
  • Post-translational
    Several N-terminal processed forms are produced by proteolytic cleavage after secretion from at least peripheral blood monocytes, leukcocytes and endothelial cells. In general, IL-8(1-77) is referred to as interleukin-8. IL-8(6-77) is the most promiment form.
