The Quantikine Rat CINC-3 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure rat CINC-3 in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant rat CINC-3 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural rat CINC-3 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 rat CINC-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.
The recovery of rat CINC-3 spiked to three levels throughout the range of the assay in various matrices was evaluated.
Average % Recovery
Cell Culture Supernates (n=6)
EDTA Plasma (n=6)
Heparin Plasma (n=6)
To assess the linearity of the assay, samples containing rat CINC-3 in each matrix were diluted with Calibrator Diluent and then assayed.
Preparation and Storage

Background: CXCL2/GRO beta/MIP-2/CINC-3
CXCL2/GRO beta, also called MIP-2 in mouse and CINC-3 in rat, is a member of the CXC chemokine family. Human CXCL2/GRO beta is 107 amino acids (aa) in length with a predicted molecular weight of 11 kDa. The mouse and rat orthologs share 70% and 71% aa sequence identity with the human protein, respectively. N-terminal aa 1-4 of CXCL2/GRO beta can be post-translationally cleaved which confers enhanced hematopoietic bioactivity. CXCL2/GRO beta is produced by a variety of cell types including monocytes and macrophages at sites of inflammation and is chemotactic for granulocytes, including neutrophils.
