C3b/iC3b/C3c, Mouse, mAb 2/11, immuno assay antibody

The monocolonal antibody 2/11 recognizes activated fragments of the mouse complement protein C3. The complement system is an important part of the humoral response in innate immunity, consisting of three different pathways. The third complement component, C3, is central to the classical, alternative and lectin pathways of complement activation. Activation products of the complement cascade contain neo-epitopes that are not present in the individual native components. The synthesis of C3 is tissue-specific and is modulated in response to a variety of stimulatory agents. C3 is the most abundant protein of the complement system with serum protein levels of about 1.3 mg/ml. An inherited deficiency of C3 predisposes the person to frequent assaults of bacterial infections. In ulcerative colitis, and idiopathic chronic inflammatory bowel disease, the deposition of C3 in the diseased mucosa has been reported. Proteolysis by certain enzymes results in the cleavage of C3 into C3a and C3b. C3b becomes attached to immune complexes and is further cleaved into iC3b, C3c, C3dg and C3f. The monoclonal antibody 2/11 is specific for cleaved C3 fragments C3b, iC3b, and C3c, and for activated C3. Therefore, positive reactivity in tissues is associated with activation of he complement cascade and C3 cleavage. In case of an acute inflammatory reaction lots of C3 are processed into the products recognized by 2/11 and is as such useful as marker for inflammatory reaction. In chronic inflammatory conditions minimal reactivity with 2/11 may observed. In such cases primarily the C3dg product resides at the place of inflammation (C3c being cleared) which is not recognized by antibody 2/11. The chronic processing/activation of C3 is taking place at a lower level, which would reduce detection of the C3 fragments C3b, iC3b, and C3c. Next to detection of C3 fragments C3b, iC3b, and C3c, the monoclonal antibody 2/11 inhibits the hemolytic activity of mouse complement in a dose-dependent manner.
