  • 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.

Thank you for contacting us. Because we carry over 70,000 products, it isn't feasible for us to keep small sample sizes of our products.

We are happy to reassure our customers that all of our products are covered by our Abpromise, which guar...

Thank you for your reply.

In theory it is possible to perform IHC-P with a directly conjugated antibody. This will also mean that the amplification that is achieve by adding the secondary is lost.

So my advise would be to only do it...

Thank you for your inquiry.

I am happy to confirm that the recommended protocol in IHC is the following:

Antigen retrieval: 5 min proteolytic enzyme (competitor), 20C

Antibody incubation: 120 min, 20C 1:500

That is great to hear. Please contact us again with any more questions or comments.

The originator of ab7747 has suggested trying recombinant IL-8 to test your system or using activated macrophages. Since you don't have the original vial, do you have the Abcam order number or the purchase order number? Do you happen to know the lot nu...
