Complement Component C5/C5a Proteome Profiler Antibody Arrays

Human complement component C5a (C5a) is an enzymatically generated glycoprotein that belongs to a family of structurally and functionally related proteins known as anaphylatoxins. C5a is a 74 amino acid (aa) peptide that is created by the activity of C5a convertase on the C5 alpha-chain. Human C5a has four alpha-helices plus three intrachain disulfide bonds that create a triple loop structure. In serum, proteolytic processing removes the C-terminal arginine, creating a low activity C5a desArg74 ...
