The invention discloses a milk
allergen test plate, which belongs to the gold immunochromatography detection. According to the milk
allergen test plate disclosed by the invention, two ends of a PVC (polrvinyl
chloride) base plate are respectively provided with a to-be-tested sample zone and an absorption zone.
Colloidal gold mark antigens prepared by respectively marking
colloidal gold into
casein,
beta lactoglobulin and
alpha lactalbumin and mixing are orderly arranged between the sample zone to be tested and the absorption zone, and a
nitrocellulose membrane is respectively provided with a detection zone coated with mixed milk
allergen and a
quality control zone coated with anti-
beta lactoglobulin antibodies. In detection, color lines are formed in the detection zone and the quality contol zone when an
immune complex is formed by specific milk antibodies contained in samples. If the samples do not contain specific milk antibodies, the detection zone does not display color, and only one color line is formed in the
quality control zone. The milk allergen test plate disclosed by the invention with the design has the advantages of strong pertinence to the allergen detection, simplicity in operation, low cost and high sensitivity and the like, and can prevent the phenomenon of
missed diagnosis in the single
antibody detection. The milk allergen test plate is applied for rapidly screening patient allergic to milk, and is especially suitable for being used by primary
medical treatment units.
