Human Complement C5a Protein

Recombinant Human C5a Protein is expressed from E.coli with His tag at the N-Terminus.It contains Thr678-Arg751. The anaphylatoxin C5a is an extremely potent proinflammatory peptide produced during activation of the complement system. The structure of C5a includes a core region (N-terminal residues 1-63) consisting of four, antiparallel alpha-helices held together by three disulfide linkages and a structured C-terminal tail (residues 64-74).
