亚洲博彩平台排名-20114 Trimethoprim rapid test strip (Tissue)

Trimethoprim rapid test strip (Tissue)

Catalog No. 亚洲博彩平台排名-20114

1. Specifications: 8 strips/bottle, 12 bottles/kit

2. Brief

This product is used for testing Trimethoprim in tissue(fish, shrimp, crab, chicken, livestock etc.) sample. Easy to operate with high sensitivity.

3. Detection limit: 5ng/g (ppb)

4. Principle

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

5. Contents

1	Trimethoprim test strips	8 strips/bottle, 12 bottles
2	Red Micro-well	8 wells/bottle, 12 bottles
3	Manual	1 piece
4	Desiccant	2 pieces/bag
5	Sample redissolving solution 10X	1 bottle

6. Solution preparation

Sample redissolving solution: Dilute Sample redissolving solution 10X with deionized water at 1:9: 1 part Sample redissolving solution 10X + 9 parts deionized water.

7. Sample preparation

Take 3±0.05g homogenized tissue sample, add 3ml Sample redissolving solution, shake for 2min; centrifuge at 4000rpm for 5min, take up-layer clear liquid to test.

8. Operation procedures

8.1 Return test strips and sample into room temperature before use.

8.2 Take necessary strips and micro-wells on desk, use it in 1 hour. Seal the unused strips and microwells, avoid moisture.

8.3 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 (this is a very important step).

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

8.5 React at room temperature (20-25℃) for 5min again, take out the test strips and read the result.

9. Test Result Interpretation

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

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

10.Specificity

Test 500ppb Tetracyclines, Quinolones, Sulfonamides and other drugs. All the results are negative.

11. Precautions

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

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

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

4) Please contact the supplier for any questions.

12. 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.
