The invention discloses a method for fast detecting allergens, belonging to the technical field of detection. The integrated type
allergen viable cell detection
system integrates
cell fixation,
allergen irritation and
histamine release and determination. The
system comprises three cavities consisting of four
layers of
dimethyl siloxane microchips, wherein the cavities are connected respectively through a
silane capillary tube, the cavity at the first layer can be connected with a flow
injector or a
syringe through a plurality of joints, the cavity at the second layer is an effect
cell cavity, and the cavity at the third layer is a
histamine reaction basin cavity. After liquid to be detected continuously and fully reacts with effect cells, a solution reaches a
histamine reaction basin through a filter membrane and fully reacts with fluorescent
derivatization liquid input in advance through reaction
liquid injection holes, the generation condition of histamine can be judged under a fluorescent
microscope according to
fluorescence intensity, and further whether the reaction liquid contains allergens can be judged. The method has excellent sensitivity, fast response and direct
visibility, the detection time can be remarkably shortened, the stability is high, and the method has great application potential in detection of allergens in
cosmetics,
food safety and clinical medicines.
