【Intended Application】

The test kit is used for the detection of tetracycline-class drugs (Tetracyclines, TCs) such as raw milk, tissue, egg and honey.  

【Principle】

The tetracycline-class drugs are broad-spectrum antibiotics, primarily including tetracycline, doxycycline, chlortetracycline, and oxytetracycline, among others.

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

If the content of TCs in the sample solution is less than detection limit, it will make the test (“T”) line colored (The color is consistent with the control line or deeper) and the result is negative. If the content is greater than detection limit, no color reaction will be produced (or color is lighter than the control line) and the result is positive.【Storage Conditions】

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

²Shelf life: 12 months. The date of manufacture is presented in the label of the box.

【Technique Data】

l Kit Sensitivity: 10ppb (ppb=µg/kg)

The final detection limit for the sample must be calculated by multiplying the kit sensitivity by the dilution ratio used in sample processing.
