2. Product overview:

Malachite green, furazolidone (AOZ), furaltadone (AMOZ), nitrofurantoin (AHD), nitrofurazone (SEM), chloramphenicol, sulfonamides, quinolones, and enrofloxacin are highly effective broad-spectrum antibiotics, commonly used in the treatment of various infectious diseases in animals, and have a strong inhibitory effect on a variety of pathogens. They have been widely used in aquatic products and livestock and poultry farming, but also brought about serious problems of chloramphenicol residues in aquatic products and livestock and poultry. Chloramphenicol has serious toxic side effects, which can inhibit the hematopoietic function of human bone marrow, cause human aplastic anemia, granulocytopenia, gray syndrome of neonates and premature infants, and low concentrations of drug residues can also induce drug resistance of pathogenic bacteria. Therefore, chloramphenicol residues in animal food pose a huge threat to human health. This product uses the principle of immunochromatography technology to qualitatively detect chloramphenicol residues in samples such as fish, shrimp, chicken, pig, and cattle. It has the characteristics of simple operation, short detection time, and can be directly interpreted by the naked eye. It is suitable for on-site rapid detection of various enterprises and testing institutions.

How to use colloidal gold card:

[Sample processing]

1. Take more than 100g of representative samples and crush them, weigh 3.0g of evenly crushed samples and add them to a 15mL centrifuge tube.

2. Accurately add 5mL of reagent A to the 15mL centrifuge tube, seal the bottle cap tightly, and mix the sample up and down for 3min.

3. Centrifuge the above sample at 4000rpm for 3min, take 3mL of supernatant in a 10mL centrifuge tube, and blow dry under nitrogen (air) in a 50~60℃ water bath.

4. Add 0.5mL of reagent B and 0.3mL of diluent, mix well, and let stand until the liquid is clearly stratified (or centrifuged at 4000rpm for 3min), and the lower layer of liquid is to be tested.

【Testing steps】

1. Before use, restore the test card and the sample solution to room temperature, take out the test card from the packaging bag, and lay the test card flat.

2. Use a disposable dropper to add 5 drops of the test solution to the sample well.

3. Start timing after adding the sample, and observe the results after 5-8 minutes. After 8 minutes, the judgment is invalid.

4. Start timing after adding the sample, operate the machine to pop up and slide within 5-8 minutes, put in the colloidal gold card to read the value, record the results, and print out the test report

Note: The dropper for adding the sample must be used once to prevent cross contamination.
