Methodology

Polystyrene particles coated with antibodies specific to human IgE are aggregated when mixed with samples containing IgE. These aggregates scatter a beam of light passed through the sample. The intensity of the scattered light is proportional to the concentration of the respective protein in the sample. The result is evaluated by comparison with a standard of known concentration.
