Catalog No. LSY-20067-e1

1. Specifications: 8 dipsticks/tube, 12 tubes/box (96tests/box)

2. Brief

This product is used for testing Enrofloxacin in eggs sample qualitatively. Easy to operate with high sensitivity.

3. Detection limit:  1ug/kg (1ppb)

5. Principle

The Enrofloxacin rapid test strip is based on competitive inhibition immuno-chromatographic principle. In the flow process, Enrofloxacin in the sample combined with Enrofloxacin specific colloidal gold-labeled monoclonal antibody, Inhibit the combination between antibody and Enrofloxacin-BSA conjugate on Test line of NC membrane, lead to the color change of Test line. When the sample has no Enrofloxacin residue or concentration lower than detection limit, T line is darker than C line or T line has same color with C line; when the concentration is equal to or higher than detection limit, T line is obviously lighter than C line or T line has no color. No matter whether there is Enrofloxacin residue in sample, C line will appear, it means the test is valid.

6. Sample preparation

Weigh 3 ± 0.05 g of egg liquid (stir well), add 3ml of Sample extracting buffer, shake for 1 minute, and centrifuge for 5 minutes. Take the supernatant for testing.

7. Operation procedures

7.1 Read the instruction carefully before use. Return test strips and sample into room temperature.

7.2 Take tubes needed from the kit package, take out required microwells and strips, making proper marks. Please use these test strips within 1h. Seal the cap of the tubes, avoid moisture.

7.3 Take 200ul of the test samples into the micro-wells, then slowly aspirate multiple times to mix the sample with the reagent in the micro-wells completely until no solid judge by eyes(this is a very important step).

7.4 Incubate for 5min at room temperature (20-25℃), then insert the test strips into the micro-wells with the "MAX" end fully dipped in to the mixture solution.

7.5 Insert the test strips into micro-wells for 5min then read the result, it is invalid in other time.

8. Test Result Interpretation

8.1 Negative: T line is darker than C line, or T line has same color with C line. It means there is no Enrofloxacin residue in sample or the residue is lower than detection limit.

8.2 Positive: T line is obviously lighter than C line or T line is invisible. It means the Enrofloxacin residue is equal to or higher than detection limit.

8.3 Invalidation: C line isn’t seen wine red. It means the test strip is out of efficacy, out of date or improper operation. Please run the test again using another package. If the invalid tests keep happening, please contact the supplier.   

9. Precautions

1) The test strips can be used only once at room temperature, do not use test strips out of expiry date.

2) Do not touch the white membrane surface in the middle of test strips, avoid sunlight and fan blowing directly.

3) Use the test strips testing again for positive results.

4) Please contact the supplier for any questions.

10. Specificity

500 ppb of tetracyclines, Ciprofloxacin, Norfloxacin and other drugs were tested, and the results were negative.

11. Storage and expiry date

Storage:  Store at 2～8℃ in dark, sealed, dry place, no frozen.

Expiry date: 12 months; date of production is on box.
