The Quantikine Mouse CCL21/6Ckine Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse 6Ckine in tissue culture supernates, serum, and plasma. It contains E. coli-expressed recombinant mouse 6Ckine and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant mouse 6Ckine. Results obtained using natural mouse 6Ckine showed dose response curves that were parallel to the standard curves obtained using the Quantikine mouse kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse 6Ckine.
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.
The recovery of mouse 6Ckine spiked to levels throughout the range of the assay was evaluated.
Average % Recovery
Cell Culture Media (n=4)
To assess the linearity of the assay, samples containing high concentrations of mouse 6Ckine were 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.
CCL21, also known as 6Ckine, TCA-4, SLC, Exodus-2, and A21, is a homeostatic chemokine that signals through CCR7 or CXCR3. CCL21 is constitutively presented on initial lymphatic vessels, high endothelial venules (HEV), and lymph node dendritic cells (DC) where it promotes the docking of DC to lymphatic vessels and the retention of T cells by lymph node DC, resulting in T cell priming for activation. Its upregulation during chronic inflammation or tissue damage promotes fibrosis, inflammatory cytokine production, and neuropathic pain. The soluble chemokine is elevated in rheumatoid arthritis synovial fluid and in the serum of coronary artery disease patients.
