The Quantikine Human Chemerin Immunoassay is a 3.5 hour solid-phase ELISA designed to measure human Chemerin in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human Chemerin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Chemerin 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 Chemerin.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.
The recovery of Chemerin spiked to levels throughout the range of the assay was evaluated.

Cell Culture Media (n=8)
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of Chemerin were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Chemerin, also known as Tazarotene-induced Gene 2, (Tig-2), is a member of the Cystatin superfamily. Chemerin is synthesized as a 163 aa precursor that contains a hydrophobic 20 aa N-terminal sequence, an intervening 137 aa Cystatin fold-containing domain, and a six aa C-terminal prosegment. It is activated by proteases of the coagulation, fibrinolytic, and inflammatory cascades. Chemerin is a chemoattractant for cells bearing the Chem R23 receptor, including plasmacytoid dendritic cells and tissue macrophages.
