Recommended Concentration

This antibody functions as an ELISA detection antibody when paired with Mouse Anti-Human C‑Reactive Protein/CRP Monoclonal Antibody (Catalog # MAB17073).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human C-Reactive Protein/CRP DuoSet ELISA Kit (Catalog # DY1707) for convenient development of a sandwich ELISA or the Human C-Reactive Protein/CRP Quantikine ELISA Kit (Catalog # DCRP00) for a complete optimized ELISA.


Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Data Example

Human C‑Reactive Protein/CRP ELISA Standard Curve. Recombinant Human C-Reactive Protein/CRP protein was serially diluted 2-fold and captured by Mouse Anti-Human C-Reactive Protein/CRP Monoclonal Antibody (Catalog # MAB17073) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human C-Reactive Protein/CRP Monoclonal Antibody (Catalog # MAB17072) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background: C-Reactive Protein/CRP

CRP is a secreted protein that belongs to the Pentraxin family. It circulates as a non-covalent homopentamer. The CRP concentration in human plasma is highly increased during acute phase response to tissue injury or infection.
