  • Product nameAnti-IL8 antibody
    See all IL8 primary antibodies
  • Description
    Goat polyclonal to IL8
  • SpecificityAnti-Human IL8 will neutralize the biological activity of both rhIL8 and natural human IL8. It will not neutralize the biological activity of rhGROalpha. By immunoblotting, the antibody shows <1% cross-reactivity with rhGROalpha, rhGRObeta, rhGROgamma, and MIP2. In addition, by ELISA, it shows no cross-reactivity with other cytokines tested.
  • Tested applicationsIHC-Fr, ICC/IF, Neutralising, ELISA, WBmore details
  • Species reactivity
    Reacts with: Human
  • Immunogen

    Recombinant full length protein (Human).

  • Positive control
  • General notesNeutralization: the antibody has the ability to neutralize the biological activity of natural and recombinant IL-8. To measure the ability of the antibody to neutralize the chemo-attractant activity of rhCXCL8 for BaF/3 cells transfected with hCXCR2 cells, rhIL-8 is preincubated with various dilutions of the antibody for 30 minutes at room temperature in a 96-well plate. Following this preincubation, 75 ul of the cytokine-antibody solution (containing rhIL-8 at a final concentration of 20 ng/mL and antibody at concentrations from 0.01-20 ug/ml) was transferred to the lower compartment of a 96 well chemotaxis chamber. The chamber was then assembled using a PVP-free polycarbonate filter (5 mm pore size) and 0.2 x 10E4 cells/well was added to the top chamber. After incubation for 3 hours at 37 °C in a 5% CO2 humidified incubator, the chamber was disassembled and the cells that migrated through to the lower chamber were transferred to a working plate and quantitated overnight. The fluorescence was then read in a fluorescent plate reader set at 544/590 nm. The ND50 of the antibody is defined as the concentration of antibody resulting in a one-half maximal inhibition of bioactivity of rhIL-8 that is present at a concentration just high enough to elicit a maximum response.



Our Abpromise guarantee covers the use of ab10769 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
IHC-Fr Use a concentration of 0.5 - 5 µg/ml.
ICC/IF Use a concentration of 5 - 15 µg/ml.
Neutralising Use a concentration of 0.01 - 20 µg/ml. Please see the General Notes section for detail.
ELISA Use a concentration of 0.5 - 1 µg/ml.
WB Use a concentration of 0.1 - 0.2 µg/ml. Predicted molecular weight: 11 kDa. Able to detect rhIL-8 at 5ng/lane under non-reducing and reducing condetions.


  • FunctionIL-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 similaritiesBelongs 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.

Anti-IL8 antibody images

  • ab10769 staining IL8 in Human HUVEC cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with Triton X-100 0.1% in PBS and blocked with 10% serum for 30 minutes at 25°C. Samples were incubated with primary antibody (1/50 in culture medium) for 16 hours at 4°C. A Cy2®-conjugated Rabbit anti-goat polyclonal (1/500) was used as the secondary antibody.
