Total U87-MG cell lysates (negative control) and human serum protein (15µg protein) were resolved by 4-12% Bis-tris gel electrophoresis, transferred to nitrocellulose, and probed with 1µg/mL purified anti-CRP antibody (clone A16065C) antibody (upper). Proteins were visualized using a goat anti-mouse-IgG secondary antibody conjugated to HRP and chemiluminescence detection. Ponceau S staining was used as loading controls (lower). Lane M is the molecular weight ladder.

    IHC staining using purified anti-CRP (C-reactive protein) antibody (clone A16065C) on formalin-fixed paraffin-embedded human liver tissue. Following antigen retrieval using 1X Tris-EDTA buffer (100 mM Tris, 10 mM EDTA, pH 9.0), the tissue was incubated with 10 µg/mL of antibody overnight at 4°C, followed by incubation with 2.5 µg/mL of Alexa Fluor® 647 goat anti-mouse IgG antibody (Cat. No. 405322) for one hour at room temperature. Nuclei were counterstained with DAPI (blue) (Cat. No. 422801), and the slide was mounted with ProLong™ Gold Antifade Mountant. The image was captured with a 40X objective. Scalebar = 50 µM.

Description

C-reactive protein (also known as CRP and Pentraxin 1 (PTX1)), is a member of pentraxin protein family. Similar to other pentraxins, CRP is a pattern recognition molecule that is able to recognize pathogens and promote their clearance. CRP tends to form a non-covalently linked pentamer with each subunit made up of two antiparallel β-sheets and a single short α-helix. It is characterized by the presence of a cleft that extends from the center of the subunit to its edge at the central pore of the pentamer structure. It has been demonstrated that CRP binds to the phosphocholine moieties expressed on the surface of dead or dying cells and some bacteria. This leads to the activation of the complement system and promotion of phagocytosis by macrophages to clear necrotic and apoptotic cells. CRP is secreted by hepatocytes and is a biomarker for inflammation. IL-6 has been shown to be an effective inducer of this protein. Besides binding to apoptotic cells, CRP also binds to a variety of molecules including C1q, bacterial polysaccharide, CD64, CD32, APCS, HDL, and fibronectin. In addition to participating in immune responses, CRP is also a prominent partaker in endothelial dysfunction and atherosclerosis. It was shown that CRP may exhibit direct proantherogenic effects by upregulating angiotensin type I receptor in smooth muscle cells and promoting their migration, proliferation, neointimal formation, and reactive oxygen species production. Mature human CRP shares 71% amino acid sequence homology with its mouse counterpart.
