Human CCL13 (Chemokine C-C-Motif Ligand 13) Microsample ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human CCL13. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CCL13. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human CCL13, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human CCL13 in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 15.63-1000 pg/mL. Sensitivity: 6.7 pg/mL. Assay Type: Sandwich. Standard: 1000 pg/mL. Sample Type: sserum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids. Assay duration: 3.5h. Protein Function: Chemotactic factor that attracts monocytes, lymphocytes, basophils and eosinophils, but not neutrophils. Signals through CCR2B and CCR3 receptors. Plays a role in the accumulation of leukocytes at both sides of allergic and non-allergic inflammation. May be involved in the recruitment of monocytes into the arterial wall during the disease process of atherosclerosis. May play a role in the monocyte attraction in tissues chronically exposed to exogenous pathogens [The Uniprot Consortium]
