Rapid detection test strip for imidacloprid

Rapid detection test strip for imidacloprid

Product Introduction:
This product uses colloidal gold immunochromatography technology to detect pesticide residues of imidacloprid in vegetables and fruits, with the characteristics of simple operation and short detection time.

Scope of application
This product is suitable for on-site or laboratory rapid detection of pyrethroid pesticide residues in vegetables and fruits.
The verified sample types are as follows:
Vegetables: bamboo shoots, purple cabbage, Chinese cabbage, Sichuan pepper, cucumber, lettuce, mustard greens, celery, green beans, garlic, edamame, taro, spinach, water chestnuts, lettuce, onion, radish, sweet potato, pumpkin, bitter gourd. Fruits: peaches, apples, watermelons, mangoes, oranges, coconuts, grapes.

Detection Principle
This product uses colloidal gold immunochromatography technology to freeze dry gold labeled antibodies in the detection micropores. The detection line (T line) and control line (C line) of the nitrocellulose membrane are separately coated with imidacloprid antigen and sheep anti mouse IgG secondary antibody. If the sample contains fenitrothion, it binds to the colloidal gold labeled monoclonal antibody of fenitrothion during microporous incubation, thereby inhibiting the binding of the gold labeled antibody to the fenitrothion antigen coated on nitrocellulose membrane. If the color of the T-line is weaker than that of the C-line or does not show color, that is, the content of imidacloprid in the sample is equal to or exceeds the product detection limit, otherwise it is lower than the product detection limit.

sample pretreatment
1. Take 2 g ± 0.1 g of the crushed sample and add it to a 15 mL or 50 mL centrifuge tube.
2. Measure and add 8 mL of sample universal extraction solution, shake thoroughly and mix well to obtain the test solution.
