Application

Interleukin-8 (IL-8) human has ben used to:
  • measure neutrophil chemotoxis
  • study the uptake of apoptotic cells by meningothelial cells
  • study the effect of IL-8 on expression and secretion of urocortin-1 by human umbilical vein endothelial cells

Biochem/physiol Actions

Interleukin-8 (IL-8) was formerly called monocyte-derived neutrophil chemotactic factor. It belongs to the chemokine α or C-X-C family. Like other members of this family, the mature form of IL-8 has four cysteine residues and the first two cysteine residues are separated by glutamine. IL-8 shows chemotactic activity in vitro for T cells, neutrophils and basophils. Mutation in IL-8 can increase risk to acute pancreatitis.
Interleukin-8 (IL-8), formerly called monocyte-derived neutrophil chemotactic factor, belongs to the chemokine α or C-X-C family. The mature form of IL-8 has 4 cysteine residues, as do the other members of the chemokine family and the first two cysteine residues are separated by glutamine. Mature human IL-8 consists of 72 amino acids with a molecular mass of 8.4 kDa. IL-8 exhibits chemotactic activity in vitro for T cells, basophils, as measured by enzymes including myeloperoxidase, α-mannosidase and β-glucuronidase. IL-8 is an angiogenic factor.

Physical form

Lyophilized from a 0.2 μm filtered solution with no additives.

Analysis Note

The biological activity is determined by its ability to chemoattract human peripheral blood neutrophils using a concentration range of 10.0-100.0 ng/ml.

Urocortin 1 (Ucn1) is a 40-amino-acid peptide that has vasodilatory activity and displays immunomodulatory and antioxidant properties. Maternal and cord plasma Ucn1 levels are increased in preeclampsia and preterm labor, but the mechanisms of such increase are poorly known. Thus

It is known that advanced metabolic disorders such as type 2 diabetes compromise the functional and regenerative capacity of endogenous adipose-tissue resident stem cells (ADSCs). It is, however, still unclear at which stage of disease progression ADSCs become compromised and

Basophils from five of six human donors released histamine in response to neutrophil attractant/activation protein-1 (NAP-1). Histamine release by this protein was concentration-dependent over the range of 3 x 10(-7) M to 4 x 10(-6) M. At 4 x 10(-6)

In diabetes mellitus, there is a problem of both premature atherosclerosis as well as impaired collateralization. Studies were performed using the rat corneal angiogenesis model as a surrogate for collateralization to determine the effect of diabetes mellitus on endothelin (ET)-1
