Product details

Human IL-8 ELISA Kit ab214030 is a rapid single-wash 90-min ELISA kit to measure Human IL-8 in cerebral spinal fluid, cell culture supernatant, serum and plasma. This SimpleStep ELISA® sensitivity is 1.8 pg/mL.

How the assay works
Human IL-8 SimpleStep ELISA® employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.

Assay Specificity
This kit recognizes both native and recombinant human IL-8 protein in serum, plasma, and cell culture supernatant samples only. Cell and tissue extract samples have not been tested with this kit.

Human IL-8 ELISA Kit ab214030 protocol summary:

2. Wash
3. Add TMB development solution - incubate for 10 min
4. Add stop solution
5. Read the results on a plate reader at 450nm

Related and recommended products
Human IL-8 ELISA Kit ab214030 is commonly used to measure IL-8 as a marker of inflammation.

Other ELISA kits to measure inflammatory markers include:
- Human TNF alpha ELISA kit ab181421
- Human IL-6 ELISA kit ab178013
- Human IL-1 beta ELISA kit ab214025

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.

Target data

Chemotactic factor that mediates inflammatory response by attracting neutrophils, basophils, and T-cells to clear pathogens and protect the host from infection (PubMed : 18692776, PubMed : 7636208). Also plays an important role in neutrophil activation (PubMed : 2145175, PubMed : 9623510). Released in response to an inflammatory stimulus, exerts its effect by binding to the G-protein-coupled receptors CXCR1 and CXCR2, primarily found in neutrophils, monocytes and endothelial cells (PubMed : 1840701, PubMed : 1891716). G-protein heterotrimer (alpha, beta, gamma subunits) constitutively binds to CXCR1/CXCR2 receptor and activation by IL8 leads to beta and gamma subunits release from Galpha (GNAI2 in neutrophils) and activation of several downstream signaling pathways including PI3K and MAPK pathways (PubMed : 11971003, PubMed : 8662698).
