The Quantikine Human MCP-3 Immunoassay is a 4.5 hour solid phase ELISA designed to measure MCP-3 levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human MCP-3 and antibodies raised against the recombinant factor. Results obtained for naturally occurring human MCP-3 showed linear curves that were parallel to the standard curves obtained using the kit standards. These results indicate that this kit can be used to determine relative mass values for natural human MCP-3.
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.
Serum, EDTA Plasma, Heparin Plasma
Cell Culture Supernates
The recovery of MCP-3 spiked to levels throughout the range of the assay in various matrices was evaluated.
Average % Recovery
Cell Culture Media (n=4)
EDTA Plasma (n=5)
Heparin Plasma (n=5)
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of MCP-3 were serially diluted with the appropriate 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.
Human MCP-3 and mouse MARC are members of the CC subfamily of chemokines and are monocyte chemoattractants. Sequence comparisons suggest that MARC may be the mouse homolog of the human MCP-3 gene. Except for one amino acid subsititution, mouse MARC is identical to mouse FIC, the product of a growth factor-activated gene.
