Product details:
Human IL-8 Matched Antibody Pair Kits include a capture and a biotinylated detector antibody pair, along with a calibrated protein standard, suitable for sandwich ELISA. The Matched Antibody Pair Kit can be used to quantify native and recombinant human IL-8.Optimization of the kit reagents to sample type, immunoassay format or instrumentation may be required. Guidelines for use of this kit in a standard 96-well microplate sandwich ELISA using HRP/TMB system of colorimetric detection is described in this assay procedure for the purposes of quantification.Protocol information and tips on the use of the Matched Antibody Pair kits for sandwich ELISA can be found on our . An accessory pack can be purchased which includes buffer reagents required to perform 10 x 96-well plate sandwich ELISAs (

IL-8 also known as CXCL8 is a cytokine with a molecular weight of approximately 8 kDa. It belongs to the CXC chemokine family and plays a role in the recruitment of neutrophils to sites of inflammation. Cells like monocytes macrophages and endothelial cells express IL-8 after activation by pro-inflammatory signals. The protein exhibits high expression in cells associated with the immune response and inflammation serving as a signaling molecule between these cell types.
Biological function summary
IL-8 functions as a chemoattractant for neutrophils and lymphocytes facilitating their movement towards the site of infection or injury. It does not form part of a larger protein complex but operates individually to enhance immune cell migration. IL-8 possesses unique binding motifs allowing it to interact with specific receptors namely CXCR1 and CXCR2 on target cells. This binding triggers cellular responses leading to effective immune surveillance and response to inflammatory stimuli.
Pathways
IL-8 operates within important inflammatory and immune response pathways. It forms a part of the NF-κB signaling cascade which activates in response to stress signals promoting the expression of other inflammatory mediators. Additionally it engages in the mitogen-activated protein kinase (MAPK) pathway influencing cellular responses such as proliferation and differentiation. The interaction of IL-8 with these pathways highlights its role in modulating immune responses and highlights its interaction with other proteins such as TNF-α and IL-1β.
IL-8 shows a strong association with conditions like rheumatoid arthritis and chronic obstructive pulmonary disease (COPD). It acts as a biomarker for these diseases often correlating with disease severity and inflammation levels. In rheumatoid arthritis IL-8 contributes to joint inflammation and degradation while in COPD it enhances airway inflammation and tissue damage. The cytokine's involvement in these diseases connects it with other inflammatory mediators such as MMPs and leukotrienes which collectively exacerbate disease pathology.
