Beta Lactams Tetracyclines and Sulfonamides Combo Rapid Test Strip 96 Tests/Kit
1. Specifications
8 strips/bottle, 12 bottles/kit
2. Brief
The Beta-lactams, Tetracyclines and Sulfonamides combo rapid test
strip is based on Colloidal gold immunochromatography, used for
testing Beta-lactams, Tetracyclines and Sulfonamides residue in
milk(including pure milk and fresh milk) and goat milk
qualitatively. The whole test only need 10min, east to operate with
high sensitivity.
3. Detection limit

| Penicillin G | 2~4 | Sulfadiazine (SD or SDZ) | 3-5 | Tetracycline | 5-10 |
| Amoxicillin | 2~3 | Sulfamerazine (SM1) | 3-5 | Oxytetracycline | 5-10 |
| Ampicillin | 2~3 | Sulfamonomethoxine (SMM) | 2-3 | Chlortetracycline | 5-10 |

| 3 | Desiccant | 2piece/bottle |
| 4 | Instruction | 1 piece |
5. Principle
The Beta-lactams, Tetracyclines and Sulfonamides combo rapid test
strip is based on competitive inhibition immuno-chromatographic
principle. In the flow process, antibiotics in the sample combined
with antibiotics specific colloidal gold-labeled monoclonal
antibody, Inhibit the combination between antibody and
antibiotics-BSA conjugate on Test line of NC membrane, lead to the
color change of Test line. When the concentration is equal to or
higher than detection limit, T line is lighter than C line or T
line has no color or T line has same color with C line.When the
sample has no antibiotics residue or concentration lower than
detection limit, T line is darker then C line; No matter whether
there is antibiotics residue in sample, C line will appear, it
means the test is valid.
6. Operation procedures
6.1 Read the instruction carefully before use. Return test strips
and sample into room temperature.
6.2 Take bottles needed from the kit package, take out required
microwells, making proper marks, Please use it in 1 hour. Seal the
cap of the bottles, avoid moisture.
6.3 Use Micro-pipette to take 200ul of the samples into the
microwells, then repeatedly absorb for 5 times, mix the sample with
the reagent in the microwells completely until no solid judged by
eyes (this is a very important step).
6.4 Incubate at 40±2℃for first step, timing for 5 min.
6.5 Then insert the strip into micro-well, put the end with MAX
down into the liquid. Then incubate at 40±2℃for second step, timing
for 5 min, then read the result as Picture 1.
7. Test Result Interpretation
| Color depth comparison of T line and C line | Result judgment | Result analysis |
| T line > C line | Negative | Antibioticsresidue 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 strip is invalid, test again |
8. Precautions
1) This product is suitable for pure milk and goat milk, fresh
milk.
2) The test strip is used for once at room temperature, do not use
test strip out of date.
3) Cover the bottle immediately after taking out the reagent. If
can’t use 8 micro-wells for one time, cover the micro-wells
immediately and put back to the bottle, store in seal.
4) Do not touch the white membrane surface in the middle of test
strip, avoid sunlight and fan blowing directly.
5) Store the milk sample in cold, no more than 3 days.
6) Milk samples should be fully liquid without any agglomeration,
sour and precipitation. Mix and stir sample evenly before testing.
7) For high-fat sample,Chromatography speed is slow, recommend to
extend second step for another 1 min.
8) Use the test strips testing again for positive results.

This product has no cross-reaction with Quinolones, Chloramphenicol
and Melamine etc.
