- Extra Details:
- C5a is a protein fragment released from complement component C5. In humans, the polypeptide contains 74aa. NMR spectroscopy proved that the molecule is composed of four helices and loops connecting the helices. On the N terminal a short 1.5 turn helix is also present. The longest helix -IV- develops three disulfide bonds with helix II and III. C5a is rapidly metabolised by a serum enzyme, carboxypeptidase B to a 73aa form, C5a des-Arg. C5a binds to a receptor protein on the surface of target cells, C5aR or CD88. This is a member of the G-protein-coupled receptor superfamily of proteins, predicted to have seven transmembrane helical domains of largely hydrophobic aa residues, forming three intra-and three extra-cellular loops, with an extracellular N-terminal and an intracellular C-terminal. Applications: Suitable for use in ELISA, Western Blot, Immunohistochemistry, Immunocytochemistry. Other applications not tested. Recommended Dilution: ELISA: 1:100-5000 Western Blot: 1:50-400 Immunohistochemistry (frozen): 1:50-500 Immunohistochemistry (paraffin): 1:10-100 Immunocytochemistry: 1:50-500 Optimal dilutions to be determined by the researcher.
