一般描述
SILu™Lite CRP is a recombinant human protein expressed in human 293 cells. It is a protein consisting of 226 amino acids (including a C-terminal polyhistidine and FLAG® tags), with a calculated molecular weight of ~25 kDa. SILu™Lite CRP is an analytical standard designed to be used as starting material for preparation of calibrators and controls in LC-MS applications.

生化/生理作用
CRP is a hepatically derived pentraxin. It exists mainly as a pentamer in a cyclic structure with 5 identical 23-kD subunits in the blood. In addition to its role as an "acute phase" protein or first-line defense molecule against pathogenic organisms, baseline levels of CRP correlate positively to adverse cardiovascular events. CRP is therefore being considered a “risk factor” for cardiovascular disease. In humans, treatment with statin therapy reduces levels of both LDL-C and CRP, and concurrently there is a reduction in the number of cardiovascular events. A recent study suggests that patients with elevated basal levels of CRP are at an increased risk of diabetes, in addition to cardiovascular disease. A study of over 700 nurses showed that those in the highest quartile of trans fat consumption had blood levels of CRP that were 73% higher than those in the lowest quartile.
