anti-complement factor H is an enzyme linked immunosorbent assay designed to detect IgG antibodies against complement factor H. The wells of the microtitrate plate are coated with purified human complement factor H. Antibodies against factor H present in serum sample bind to the immobilized factor H. Other antibodies, unbound to the factor H, are washed away during the next step. Then anti-human IgG antibodies labelled with horseradish peroxidase are added and those detect the antibodies from the sample that previously bound to factor H. The unbound labelled antibodies are washed away and the remaining labelled antibodies are visualized with a chromogenic substrate. The peroxidase activity leads to a change in colour of the solution. The reaction is stopped by adding an acidic solution. The colour intensity is directly proportional to the amount of anti-factor H antibodies in the sample.
