Erythromycin Lincomycin and Kanamycin Combo Rapid Test Strip 96 Tests/Kit
1. Brief
The Erythromycin, Lincomycin and Kanamycin combo rapid test strip
is based on Colloidal gold immunochromatography, used for testing
Erythromycin, Lincomycin and Kanamycin 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.
2. Detection limit
Drug | Detection limit (ppb) |
Erythromycin | 5-10 |
Lincomycin | 2-3 |
Kanamycin | 3-5 |
3. Contents
1 | Test strip | 8strip/bottle |
2 | Red powder micro-well | 8 micro-well/bottle |
3 | Desiccant | 2piece/bottle |
4 | Instruction | 1 piece |
4. Principles
The erythromycin, lincomycin and kanamycin combination rapid test
strips are based on the principle of competitive inhibition
immunochromatography. During the process, the antibiotic in the
sample binds to the antibiotic-specific colloidal gold-labeled
monoclonal antibody, which inhibits the binding of the antibody to
the antibiotic-BSA conjugate on the NC membrane detection line,
resulting in discoloration of the detection line. When the
concentration is at or above the detection limit, the T line is
lighter than the C line or the T line has no color or the T line is
the same color as the C line. When there is no antibiotic residue
in the sample or the concentration is below the detection limit,
the T line is darker than the C line; regardless of whether there
is any antibiotic residue in the sample, the C line will appear,
indicating that the detection is effective.
5. Operation procedures
5.1 Read the instruction carefully before use. Return test strips
and sample into room temperature.
5.2 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.
5.3 Use Micro-pipette to take 200ul of the samples into the
microwells, then repeatedly pump and suck for 5-10 times, mix the
sample with the reagent in the microwells completely until no solid
judged by eyes (this is a very important step).
5.4 Incubate at 40±2℃for first step, timing for 5 min.
5.5 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
5.5 Take out strips from the micro-wells, read the result as
Picture 1.
6. 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 |
7. 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.
8. Specificity
This product has no cross-reaction with Chloramphenicol,
Sulfonamides and Melamine etc.
