2、 Product Overview:

Malachite green, furazolidone (AOZ), furantadone (AMOZ), nitrofuran (AHD), furacilin (SEM), chloramphenicol, sulfonamides, quinolones, and enrofloxacin are highly effective broad-spectrum antibiotics commonly used in the treatment of various infectious diseases in animals. They have strong inhibitory effects on multiple pathogens and have been widely used in aquaculture and livestock farming, but have also caused serious problems with chloramphenicol residues in aquatic products and livestock. Chloramphenicol has serious toxic side effects, which can inhibit the hematopoietic function of the human bone marrow, causing diseases such as aplastic anemia, granular cell deficiency, gray syndrome in newborns and premature infants. Low concentrations of drug residues can also induce drug resistance in pathogenic bacteria. Therefore, chloramphenicol residues in animal food pose a huge threat to human health. This product utilizes the principle of immunochromatography technology to qualitatively detect chloramphenicol residues in samples such as fish, shrimp, chicken, pigs, and cattle. It has the characteristics of simple operation, short detection time, and direct visual interpretation of results, and is suitable for rapid on-site detection by various enterprises and testing institutions.

Instructions for using colloidal gold cards:

6、 Steps of chloramphenicol detection method

Sample Processing

1. Take over 100g of representative sample and crush it. Weigh 3.0g of evenly crushed sample and add it to a 15mL centrifuge tube.

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

3. Centrifuge the above sample at 4000rpm for 3 minutes, take 3mL of supernatant and transfer it to a 10mL centrifuge tube. Blow dry it under nitrogen (air) in a water bath at 50-60 ℃.

4. Add 0.5mL of reagent B and 0.3mL of diluent, mix well, let it stand until the liquid is clearly stratified (or centrifuge at 4000rpm for 3 minutes), and test the lower layer of liquid.

[Testing steps]

1. Before use, restore the detection card and the sample solution to room temperature, remove the detection card from the packaging bag, and lay it flat.

2. Add 5 drops of the test solution into the sample well using a disposable dropper.

3. After adding the sample, start timing and observe the results within 5-8 minutes. After 8 minutes, the interpretation is invalid.

4. After adding the sample, start timing. Within 5-8 minutes, operate the machine to pop up the slide, insert the colloidal gold card to read the values, record the results, and print out the test report

Attention: The dropper used for adding samples must be disposable to prevent cross contamination.
