【Intended Application】

The test kit is used for detecting Sulfonamides (SAs) in various samples, including tissues (from fish, shrimp, crab, livestock, and poultry), honey, milk, poultry eggs, water samples, and more.

【Principle】

The kit is developed using the principle of competitive colloidal gold Immunochromatographic Assay (GICA). After the sample solution is added to sample hole, if SAs is present, it will bind with gold labeled antibodies, thereby preventing the labeled antibodies from binding to the SAs conjugates on the nitrocellulose membrane.

If the content of SAs in sample solution is less than detection limit, it will make the test (“T”) line colored, and the result is negative. If the content is greater than detection limit, no color reaction will be produced, and the result is positive.

【Storage Conditions】

The kit shall be stored at 2℃ to 30℃ in dry environment.

Shelf life: 12 months. The date of manufacture is presented in the label of the box.

【Technique Data】
