C-reactive protein (CRP) has cholesterol-binding, complement C1q complex-binding, and low-density lipoprotein particle-binding activities, and plays a role in complement activation, gene expression regulation, and superoxide anion generation. It is located in filopodia and growth cones and is expressed in embryos and liver. C-Reactive Protein, Mouse (HEK293, His) is the recombinant mouse-derived C-Reactive protein, expressed by HEK293 , with C-His labeled tag.
