Description
C-reactive protein (CRP) is synthesized by the liver in response to factors released by fat cells. It is a member of the pentraxin family of proteins. The levels of CRP rise in response to inflammation. Human C-reactive protein (CRP) is the classical acute phase reactant, the circulating concentration of which rises rapidly and extensively in a cytokine-mediated response to tissue injury, infection and inflammation. Serum CRP values are routinely measured, empirically, to detect and monitor many human diseases. However, CRP is likely to have important host defence, scavenging and metabolic functions through its capacity for calcium-dependent binding to exogenous and autologous molecules containing phosphocholine (PC) and then activating the classical complement pathway. CRP may also have pathogenic effects and the recent discovery of a prognostic association between increased CRP production and coronary atherothrombotic events is of particular interest.
Form
Lyophilized from sterile 20mM Tris, 0.2M NaCl, 5mM CaCl2, pH 8.0, 5 % trehalose, 5% mannitol and 0.01% Tween80.
Molecular Mass
The recombinant human CRP consists of 206 amino acids and has a predicted molecular mass of 23 kDa. As a result of glycosylation, the apparent molecular mass of CRP is approximately 26 kDa in SDS-PAGE under reducing conditions.
