FIELD: medicine.
SUBSTANCE: ferric (III) hexacyanferrate (II) hydrosol conjugated with antibodies (antigens) to a required analyte is used as a disperse phase. The presence of the analyte is detected by observing a bright blue strip on an analytical membrane.
EFFECT: faster immunoassay procedure as compared to conventional ones, higher contrast between an analytical zone and a white surface of the membrane.
