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.

Thank you for contacting us.
1. If you prefer to do the incubation at room temperature you should not exceed a 2 hour incubation. We do recommend an overnight incubation at 4 degrees, however, as this usually gives the strongest and most specific staining.
2. I would suggest you use ab6672 at 1/400 and ab18672 at 1/2000.
3. I believe lung cancer tissue is a good positive control for these antibodies but am not sure that the levels in normal tissue are high enough. For ab18672 we have seen good expression in lymph node, poocine epithelial tissue, and human temporal artery. For ab6672 human and mouse pancreatic cancer, head and neck tumor, and human liver sections have shown good results. Any tissue reported in the literature to have good IL6 or IL8 expression should be a good positive control if you do not have access to these tissues.
I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your reply.

I fully understand your concerns regarding the product code typing error on the datasheet, it is regrettable. I would like to reassure you that the image is from ab18672 IL8 antibody [807], and came from an Abreview submitted by a customer which is published on the Abreview page of the datasheet:


I can confirm that any publications that we are aware of will be listed on the datasheet. We have a dedicated team who spend time reviewing the literature to find articles that have used our products. However, in many cases, regrettably we do not have access to all the articles mentioning our products, or subscriptions to all the journals that publish them. I'm sorry there are no others to provide on this occasion for ab18672.

Regarding the product quality, I would like to reassure you that we monitor feedback closely on a weekly basis and we are not currently concerned about the general quality of this antibody or this batch. Regrettably, I can suggest you have received a bad vial on this occasion. Therefore, we would be pleased to provide a replacement from the same antibody, which will still be covered by our guarantee. Alternatively, I fully understand your concerns and if you prefer an alternative replacement or credit note in this case, I will be pleased to arrange this for you.

I hope this will be helpful. I look forward to hearing from you with details of how you would like to proceed.

Thank you for contacting us.

Unfortunately there is no information available about the epitope recognised by these two antibodies, as it hasn’t been mapped.

I am very sorry I couldn’t help you further. Please do not hesitate to contact us if you need any other advice or information.

Thank you again for your call last week and for your patience while I have reviewed your images and these proteins.

For ab18672 (IL8), I think the diffuse bands are caused bya bittoo much proteinloaded in the lanes orfrom running the gel at too high a voltage. You can try to load a bit less protein and lower the voltage during electrophoresis. It's also possible that the two isoforms of IL8 are being expressed and since they're so close in MW, they are resulting in a thicker band, but I would still try the other alterations to see if they tighten the bands.

Ab24598 (thrombomodulin) is probably picking up glycosylated forms of the protein, which has 7 known glycosylation sites. Each glycosylation can add 2 kDa to the predicted molecular weight of the amino acid sequence (around 60 kDa). There may be differentially glycosylated forms of the TM in your sample. I found a reference showing a similar doublet around this MW as well (see attached).

The results with thePTG antibody, ab103300, area little harder to analysis. I've looked through a lot of literature, but there are not many Western blots showing the endogenous molecular weight. Generally the protein shows up between 35 and 38 kDa, and the variance could be caused by different electrophoretic running conditions, etc, and not actual differences in the protein. Based on the information I've found, the higher band seems to be specific and the lower band is probably non-specific. According to my notes, you had tried using 5 ug/mL with this antibody, so I would suggest decreasing the amount of antibody used to reduce any non-specific binding. This should help determine the specificity of the higher band.

I hope that this information will be helpful, and if you have any questions or further comments please let me know. Please keep me updated about any new results with these antibodies. If the results are not satisfactory at any time, these antibodies are covered by our Abpromise guarantee and we can arrange a replacement, credit, or refund.

Have a nice day.
