Chemokine(C-C motif) ligand 13 (CCL13) is a small cytokine belonging to the CC chemokine family. Its gene is located on human chromosome 17 within a large cluster of other CC chemokines. CCL13 induces chemotaxis in monocytes, eosinophils, T lymphocytes, and basophils by binding cell surface G-protein linked chemokine receptors such as CCR2, CCR3 and CCR5. Activity of this chemokine has been implicated in allergic reactions such as asthma. CCL13 can be induced by the inflammatory cytokines interleukin-1 and TNF-alpha.
Sample Type:Cell culture supernates, serum and plasma (heparin, EDTA)
Intended Use:For quantitative detection of human CCL13 in cell culture supernates, serum and plasma (heparin, EDTA).
Sensitivity:<10pg/ml
Range:7.8-500pg/ml
Specificity:Natural and recombinant human CCL13
Test Principle:This human CCL13 BioAssay™ ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for CCL13 has been precoated onto 96-well plates. Standards(E.coli) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for CCL13 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human CCL13 amount of sample captured in plate.
