45x Ab-conjugated beads (S5P7 - Mouse CRP Ab-bead). PN: B216494A. One vial containing 100 µL of anti-mouse CRP conjugated to AimPlex Bead S5P7.

25x Biotin-detection Ab (Mouse CRP Biotin-dAb). PN: B216494B. One vial containing   100 µL of biotinylated anti-mouse CRP.

Lyophilized Standard Mix - Mouse CRP. PN: MCRPS. One vial containing lyophilized CRP.

Application: Optimal antibody pair and antigen standard for assaying human Mouse CRP. To be used in conjunction with the AimPlex Mouse/Rat Basic Kit (PN: P200201) and and the Mouse CRP Diluent kit (PN: P920501). Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Note: Some specimens may contain high level of CRP. For normal serum and plasma samples, diluting samples 4,000 folds with 1x Mouse CRP Assay Buffer is recommended for the CRP assay.  Dilution factors should be optimized according to specific experimental conditions and sample types.

Storage: 2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

C-reactive protein (CRP) is an annular (ring-shaped), pentameric protein found in blood plasma, whose levels rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells. Its physiological role is to bind to lysophosphatidylcholine expressed on the surface of dead or dying cells (and some types of bacteria) in order to activate the complement system via the C1Q complex.  CRP is synthesized by the liver in response to factors released by macrophages and fat cells (adipocytes). It is a member of the pentraxin family of proteins. It is not related to C-peptide (insulin) or protein C (blood coagulation). C-reactive protein was the first pattern recognition receptor (PRR) to be identified. CRP is used mainly as a marker of inflammation. Apart from liver failure, there are few known factors that interfere with CRP production. Measuring and charting CRP values can prove useful in determining disease progress or the effectiveness of treatments. Several studies investigated differential diagnostic values of CRP in a series of inflammatory disease (including inflammatory bowel disease, Intestinal Lymphoma, Intestinal Tuberculosis and Behcet's Syndrome), and compared CRP to other inflammatory biomarkers, such as ESR and WBC.
