Canine IL-8 ELISA

Interleukin-8 (IL-8), also known as CXCL8, is a CXC family member chemokine produced by macrophages and other cell types such as epithelial cells. There have been 17 different CXC chemokines described in mammals, that are subdivided into two categories, those with a specific amino acid sequence (or motif) of glutamic acid-leucine-arginine (or ELR for short) immediately before the first cysteine of the CXC motif (ELR-positive), and those without an ELR motif (ELR-negative). ELR-positive CXC chemokines such as IL-8 specifically induce the migration of neutrophils, and interact with chemokine receptors CXCR1 and CXCR2.

The Canine IL-8 Do-It-Yourself ELISA from Kingfisher Biotech contains capture antibody, standard, and detection antibody for development of a Canine IL-8 ELISA. The antibodies have been determined to function in an ELISA with the standard provided.

Bovine CCL3 (MIP-1 alpha) Do-It-Yourself ELISA, ≤10 Plates

Chemokine ligand 3 (CCL3), also known as Macrophage inflammatory protein-1 alpha (MIP-1α) is a small cytokine belonging to the CC chemokine family. There are at least 27 distinct members of the C-C subgroup reported for mammals. They are characterized by two adjacent cysteines. CC chemokines induce the migration of monocytes and other cell types such as NK cells and dendritic cells. CCL3 (MIP-1α) is a chemoattractant for several different leukocytes, with varying degrees of potency (monocytes = T-cells>neutrophils>eosinophils).

The Bovine CCL3 (MIP-1α) Do-It-Yourself ELISA contains capture antibody, protein standard, and detection antibody for development of a Bovine CCL3 (MIP-1α) ELISA. The antibodies have been determined to function in an ELISA with the standard provided.

Mouse CXCL5 Recombinant Protein

CXCL5 is a member of the CXC chemokine family and is also known as epithelial-derived neutrophil-activating peptide 78 (ENA-78). It is produced following stimulation of cells with the inflammatory cytokines, including IL-1 and TNF-alpha. Expression of CXCL5 has also been observed in eosinophils, and can be inhibited with IFN-γ. CXCL5 stimulates the chemotaxis of neutrophils. CXCL5 has been shown to play a role in conditions ranging from sun burn to cystitiis and athrosclerosis. 

Kingfisher Biotech's mouse CXCL5 recombinant protein was produced in yeast so it is naturally endotoxin-free.

Emerging Roles of IL-8 in Cancer Etiology

IL-8 exerts its tumorigenic effects through both autocrine and paracrine signaling. Secretion of IL-8 by tumor cells can enhance cell survival and proliferation of the cancer cells through autocrine signaling. IL-8 also plays an important role in the tumor microenvironment, which is composed of a diverse group of cells including fibroblasts, endothelial cells, dendritic cells, and tumor-associated macrophages. A complex network of cytokines, chemokines, and other inflammatory molecules drives communication between the microenvironment and the malignant tumor cells (Todorovic-Rakovic and Milovanovic, 2013). Importantly, IL-8 is implicated in the initiation of leukocyte infiltration, neovascularization, and angiogenesis, all processes that precede invasion and metastasis of tumor cells. Cancer cells secrete IL-8, triggering the infiltration of leukocytes to the site of chemokine production. Leukocytes in turn secrete cytokines and growth factors promoting angiogenesis and cell survival (Gales et al., 2013). more...
