Beta-lactams, Tetracyclines and Cephalexin Combo rapid test card
(Cassette format)
Catalogue No.: LSY-20117A
[Product Introduction]
The Beta-lactams, Tetracyclines and Cephalexin Combo rapid test card, based on Colloidal gold immunochromatography assay method, is used for testing β-lactam antibiotics, Tetracyclines and Cephalexin residue in milk and goat milk quickly.
[Specifications]: 50 tests/kit

[Principle]
The Beta-lactams, Tetracyclines and Cephalexin Combo rapid test card is based on competitive inhibition immuno-chromatographic principle. When the antibiotics residue in sample is higher than or equal to the detection limit, it will combine with labeled antibody, then inhibit the combination between colloidal gold antibody coated antigen on T line, making T line lighter than C line or T line invisible or T line has same color with C line. Otherwise, T line is darker than C line. No matter whether there is antibiotics residue in sample, C line is visible.
[Operation procedures]
1. Return test card and sample into room temperature.
2. Take necessary test cards on desk, use it in 1 hour.
3. Put test card on desk flatly, use dropper to drop 4 drops (100μL) of sample in the Sample collect region vertically.
4. Wait for 5 min to read the result. (It’s valid in 10 minutes)
[Test Result Interpretation]
| Color depth comparison of T line and C line | Result judgment | Result analysis |
| T line > C line | Negative | antibiotics residue is lower than detection limit in sample |
| T line = C line | Weak positive | antibiotics residue is equal to detection limit in sample |
| T line < C line or T line is invisible | Positive | antibiotics residue is higher than detection limit in sample |
| C line is invisible | Invalid | The test card is invalid, test again |
