Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B IH
C5a is a single chain glycopeptide composed of 74aa, which is rapidly converted to the less potent derivate C5a des-Arg upon removal of the C-terminal arginine by carboxypeptidase B. C5a acts as a potent anaphylatoxin by binding to its high affinity receptor C5aR (or CD88) on the membrane of target cells inducing smooth muscle contraction, increased vascular permeability, degranulation of mast cells and basophils, and the release of lysosomal enzymes. In addition C5a stimulates the directed migration of neutrophils, eosinophils, basophils and monocytes. C5a is involved in inflammatory reactions seen in gram-negative bacterial sepsis, trauma, ischemic heart disease, post-dialysis syndrome and a variety of autoimmune diseases. Elevation of C5a is associated with increased cardiovascular risk in patients with advanced atherosclerosis. Also, C5a is closely associated with the capillary leak syndrome in leukemic children after bone marrow transplantation. C5a is also a marker in urine for predicting the onset of acute graft rejection after kidney transplantation and has been shown to be present in extracellular deposits in patients suffering from age-related macular degeneration (AMD).
Catalog #C7850-24G
ApplicationsSuitable for use in Western Blot, ELISA and Immunohistochemistry. Other applications not tested.
Recommended DilutionsWestern Blot: 1:50. A reduced sample treatment and SDS-PAGE was used and detected a band of ~14kD.
Immunohistochemistry (Frozen): 1:50. Tissue sections were fixed in Histochoice MB and treated with levamisole to quench endogenouse alkaline phosphatases. The primary antibody was omitted for a negative control.
Optimal dilutions to be determined by the researcher.
Postive Control Eye tissue of patient with AMD (1)
Negative Control Eye tissue of patient without AMD (1)
