Beckman Coulter Biomedical Division Lismeehan, O'Callaghan's Mills County Clare Ireland AU/DxC AU Chemistry Transferrin REF: OSR6152 Immune complexes formed in solution scatter light in proportion to their size, shape and concentration. Turbidimeters measure the reduction of incident light due to reflection, absorption, or scatter. In the procedure, the measurement of the decrease in light transmitted (increase in absorbance) through particles suspended in solution as a result of complexes formed during the antigen-antibody reaction, is the basis of this assay.
