Method Description
The determination of the soluble antigen concentration by turbidimetric methods involves the reaction with specific anti-serum to form insoluble complexes. When light is passed through the suspension formed a portion of the light is transmitted and focused onto a photodiode by an optical lens system. The amount of transmitted light is indirectly proportional to the specific protein concentration in the test sample. Concentrations are automatically calculated by reference to a calibrations curve stored within the instrument.(Package insert: Optilite IgD Kit. The Binding Site Group, Ltd; 08/2018)
