The Quantikine Mouse C-Reactive Protein/CRP immunoassay is a 4.5 hour solid-phase ELISA designed to measure CRP in mouse cell culture supernates, tissue lysates, serum, and plasma. It contains NS0-expressed recombinant mouse CRP and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant mouse CRP. Results obtained using natural mouse CRP 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 CRP.
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 kit components.
The recovery of mouse CRP spiked to levels throughout the range of the assay was evaluated.

Cell Culture Media (n=4)
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of mouse CRP in each matrix 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.
Background: C-Reactive Protein/CRP
C-Reactive Protein (CRP), also known as Pentraxin 1, is a secreted pentameric protein that functions as a sensor and activator for the innate immune response. In humans, it is a major acute-phase protein; its circulating concentration is dramatically elevated at the onset of inflammation. In mice, however, serum CRP levels increase only slightly during inflammation, and the analogous acute phase role is filled by Pentraxin 2. CRP binds, opsonizes, and induces the phagocytosis of bacteria and apoptotic cells. It regulates activation of the classical complement pathway by binding several proteins in the complement cascade as well as Fc gamma RI, Fc gamma RIIA, and Fc gamma RIIB on macrophages and dendritic cells. It also promotes dendritic cell maturation and humoral immunity. In cardiovascular disease, CRP binds to oxidized LDL, exacerbates tissue damage in myocardial infarction, and inhibits the repair of injured vascular endothelium.
