LSY-20040 Sulfonamides residues (SAs) rapid test strip eggs 96 tests/kit

Sulfonamides residues (SAs) rapid test strip (eggs)

Milk, honey, tissue sample is available

Catalog No. LSY-20040

1. Brief

This product is used for testing Sulfonamides residue in egg, duck egg sample. The total test time only need 10 min.

2. Detection limit in eggs

3. Specifications: 8 strips/bottle

4. Principle

The Sulfonamides rapid test strip is an immuno-chromatographic test, using colloidal gold immunoassay method. It relies on the competition between Sulfonamides residues in the sample and the Sulfonamides on T line, to the limited amount of dye-antibody. As a sufficient amount of drug in the sample is presenting, the drug will saturate the antibody. Consequently, it will show an extremely light or even invisible T line, indicating a positive result. On the other hand, if there is a negative sample (or the amount of the drug is lower than the minimum detectable concentration), it will generate two obvious lines in both the T and C line section.

5. Contents

Sample preparation:

Take 1g fresh even egg sample, add 3ml pure water, shake with hand or by oscillator strongly for 3 mins, ready to use.

6. Operation procedures

6.1 Read the instruction carefully before use. Return test dipsticks and sample into room temperature.

6.2 Take bottles needed from the kit package, take out required micro-wells and dipsticks, making proper marks. Please use these test dipsticks within 1h. Seal the cap of the bottles, avoid moisture.

6.3 Take 200ul of the test samples into the micro-wells, then repeatedly absorb for many times, mix the sample with the reagent in the micro-wells completely (this is a very important step).

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

6.5 Incubate for 5-8min at room temperature again, read the result, it is invalid in other time.

7. Test Result Interpretation

7.1 Negative: Red T line appears. It means there is no Sulfonamides residue in sample or the residue is lower than detection limit.

7.2 Positive: Red T line is invisible. It means the Sulfonamides residue is equal to or higher than detection limit.

7.3 Invalidation: C line isn’t seen wine red. It means the test card is out of efficacy, out of date or improper operation.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.

8. Specificity

This product has no cross reaction with Tetracyclines, Quinolones, Streptomycin etc.

9. Precautions

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

2) Every test card and dropper is single use only, to avoid cross pollution.

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

4) Tap water, distilled water and deionized water can not treat as negative control.

5) Please contact the supplier for any questions.

10. Storage and expiry date

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