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. Storage and Stability: Lyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
