C-Reactive Protein (CRP)

Scripps Laboratories is a world-leading producer and supplier of purified human C-Reactive Protein (CRP). Various purities are available and are listed below. Please visit each product page to view individual product specifications.

C-Reactive Protein (CRP) belongs to the β-globulin family of plasma proteins and derives its name from its ability to precipitate a group C polysaccharide of pneumococcus in the presence of Ca2+.

Although its physiological function is unknown, serum levels of CRP are elevated in a wide variety of acute and chronic inflammatory conditions. These conditions include most bacterial and some viral infections, rheumatic fever, rheumatoid arthritis, and many collagen diseases. CRP serum levels are also valuable in the detection and evaluation of tissue injury, acute myocardial infarction, transplant rejection, and several malignant disorders.

These preparations of CRP are isolated from human pleural fluid and is supplied as a liquid in 20mM Tris, 280 mM Sodium Chloride, 5mM Calcium Chloride, pH 8.0 ± 0.1, with Sodium Azide added as a preservative. Protein concentration is determined by nephelometry or by A280, using an extinction coefficient of 1.7 (Emg/ml = 1.7).

A discussion of the role of CRP as a marker for cardiovascular disease is available as a three part newsletter prepared by Scripps Laboratories. For further details refer to the Literature page. 

Please note that CRP Monoclonal and CRP Goat Polyclonal antibodies are also available.
