C5 component of human complement is a plasma protein consisting of two polypeptide chains,
a, b, bound by disulphide bonds. It has a molecular weight of 190000. The activated protein forms with the complement factors C6-C9 the membrane attack complex. The average concentration in plasma is about 70mg/ml.
Applications:
Suitable for use in ELISA, Immunoelectrophoresis and Double Radial Immunodiffusion. Other applications not tested.
Recommended Dilution:
Immunoelectrophoresis: 120ul against 2ul or equivalent
Double Radial Immunodiffusion (Ouchterlony): Use a rosette arrangement with 10ul in a 3mm diameter center well and 2ul serum samples (neat and serially diluted) in 2mm diameter peripheral wells.
Optimal dilutions to be determined by the researcher.
