N-Acetyl-beta -D-Glucosaminidase Release Induced by Complement Component C5a and Neutralization by Mouse Complement Component C5a Antibody. Recombinant Mouse Complement Component C5a (Catalog # 2150-C5) induces N-acetyl- beta -D-glucosaminidase release in the the dibutyryl cyclic-AMP differentiated U937 human histiocytic lymphoma cell line in a dose-dependent manner (orange line). N-Acetyl- beta -D-Glucosaminidase Release elicited by Recombinant Mouse Complement Component C5a (50 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse Complement Component C5a Monoclonal Antibody (Catalog # MAB21501). The ND50 is typically 0.1-0.5 µg/mL in the presence of cytochalasin-B.

Background: Complement Component C5a

Mouse Complement 5a (C5a) is an enzymatically generated glycoprotein that belongs to a family of structurally and functionally related proteins known as Anaphylatoxins. C5a is a 77 amino acid (aa) peptide that is created by the activity of C5a convertase on the C5 alpha -chain (1, 2). Mouse C5a has four alpha -helices, plus three intrachain disulfide bonds that create a triple loop structure (3). In serum, proteolytic processing removes the C-terminal arginine, creating a low activity C5a desArg77 molecule (1). Mouse C5a shares 60% and 82% aa sequence identity to human and rat C5a, respectively. C5a binds to a signaling G-protein coupled receptor (GPCR) (C5aR/CD88), inducing neutrophil chemotaxis and endothelial cell activation (1, 4). It also triggers an oxidative burst in macrophages and neutrophils, and induces release of histamine in basophils and mast cells (1, 4). Alternatively, it may also bind to a nonsignaling GPCR termed C5L2 whose function is yet to be determined (5).
