Serum from ten individual healthy human male donors was measured in duplicate.
Interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean CRP concentration was determined to be 535.7 ng/mL with a range of 28.1 – 1180.4 ng/mL.

Linearity of dilution is determined based on interpolated values from the standard curve. Linearity of dilution defines a sample concentration interval in which interpolated target concentrations are directly proportional to sample dilution.
Native CRP was measured in the following biological samples in a 2-fold dilution series. Sample dilutions are made in Sample Diluent NS.

Interpolated concentrations of native CRP in human serum and plasma samples.
The concentrations of CRP were measured in duplicates, interpolated from the CRP standard curves and corrected for sample dilution. Undiluted samples are as follows : serum 1 : 1000, plasma (citrate) 1 : 2000, plasma (EDTA) 1 : 1000, plasma (heparin) 1 : 1000. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean CRP concentration was determined to be 1025.5 ng/mL in serum, 1676.5 ng/mL in plasma (citrate) and 668.3 ng/mL in plasma (EDTA), and, 1062.8 ng/mL in plasma (heparin).

Product details
How the assay works
Human CRP (C-Reactive protein)SimpleStep ELISA®employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Biological function summary
CRP plays a significant role in the innate immune system by recognizing foreign pathogens and damaged cells. It does not form part of a larger complex but itself can bind to specific ligands initiating the complement cascade. This activation enhances phagocytosis by macrophages contributing to the clearance of necrotic and apoptotic cells. The CRP protein therefore acts as a fast responder in the presence of inflammation making it a useful indicator for monitoring inflammatory diseases.
Pathways
CRP operates predominantly within the acute-phase response pathway. Its production is upregulated by cytokines such as IL-6 which connects it to inflammation-signaling pathways. CRP also interacts with the complement system bridging innate and adaptive immunity. Besides CRP could indirectly influence pathways involving other inflammatory proteins like serum amyloid A and haptoglobin creating a network of responses important for managing inflammation.
