Product Summary for Human CCL18/PARC Quantikine ELISA Kit

The Quantikine Human CCL18/PARC Immunoassay is a 2.5 hour solid-phase ELISA designed to measure human CCL18 in cell culture supernates, tissue lysates, serum, plasma, and urine. It contains E. coli-expressed recombinant human CCL18 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human CCL18 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human CCL18.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components.

Recovery for Human CCL18/PARC Quantikine ELISA Kit

The recovery of human CCL18 spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 101 91-110
Tissue Lysis Buffer (n=1) 92 91-93
Urine (n=4) 104 92-112

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human CCL18 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay. Samples were diluted prior to assay.

Background: CCL18/PARC

Pulmonary and activation-regulated chemokine (PARC), also known as alternative macrophage activation-associated CC chemokine (AMAC)-1, macrophage inflammatory protein (MIP)-4, and dendritic cell chemokine (DC-CK1), is a novel CC chemokine that is highly homologous to MIP-1 alpha (61% amino acid sequence identity). In vitro, PARC mRNA expression is induced in alternatively activated macrophages by Th2 cytokines such as IL-4, IL-10 and IL-13, and inhibited by IFN-gamma.

Alternate Names
