Target Background

Interleukin 8 (IL-8) is a chemotactic factor that attracts neutrophils, basophils and T-cells during an inflammatory process. It is released from a variety cell types such as monocytes, macrophages, neutrophils and intestine, kidney, placenta and bone marrow cells in response to inflammation. It is involved many cellular processes including cell proliferation, tissue remodeling and angiogenesis. IL-8 mediates its effects by binding to two heterotrimeric G protein-coupled receptors, CXCR1 and CXCR2. Given that it is a major mediator of inflammation, IL-8 was markedly increased in infants diagnosed with perinatal infection.

Customize This Human IL-8 ELISA

We manufacture our ELISAs in-house, so we can build a custom version for your study.

  • Post-translational modifications (PTMs): Detect modified IL-8 (IL8 / CXCL8), including phosphorylation, acetylation, S-nitrosylation, S-acylation, oxidation, lactylation, sumoylation, ubiquitination, nitration, carbamylation, and more
  • Sample types: Validation in your matrix using samples you provide, such as CSF, urine, saliva, lysates, or exosomes
  • Also available: More sensitive platforms such as Simoa® and NexaTag®, multiplex panels, bulk lots, and other species when suitable reagents exist

Feasibility varies by target and modification, and we’ll tell you upfront what’s achievable.
