Erythromycin Rapid Milk Test Kit 96 Tests/Kit for Milk 3 ~ 5 ug/kg
1. Specifications
8 strips/bottle, 12 bottles/kit
2. Introduction
Erythromycin rapid test strips are used to qualitatively detect
erythromycin residues in fresh milk. The whole test only takes 10
minutes, and the operation sensitivity of Dongdong is high.
3. Detection limit
3~5ug/kg (ppb)
4. Content
| 1 | Erythromycin test strip | 8strip/bottle |
| 2 | Red powder micro-well | 8 micro-well/bottle |
| 3 | Desiccant | 2piece/bottle |
| 4 | Instruction | 1 piece |
5. Principles
The erythromycin rapid test strip is based on the principle of
competitive inhibition immunochromatography. During the process,
the erythromycin in the sample binds to the erythromycin-specific
colloidal gold-labeled monoclonal antibody, which inhibits the
binding of the antibody to the erythromycin-BSA conjugate on the
detection line of the NC membrane, resulting in discoloration of
the detection line. When the sample has no erythromycin residue or
the concentration is lower than the detection limit, the T line is
darker than the C line; when the concentration is equal to or
higher than the detection limit, the T line is lighter than the C
line or the T line has no color or the T line has the same color as
the C line. The C line will appear regardless of whether there is
erythromycin residue in the sample, indicating that the detection
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 5 min. Then insert the strip into
micro-well, put the end with MAX down into the liquid.
6.5 Insert the strip into the liquid for 5min, then read the
result.
7. Test Result Interpretation
| Color depth comparison of T line and C line | Result judgment | Result analysis |
| T line > C line | Negative | Erythromycinresidue is lower than detection limit in sample |
| T line = C line | Weak positive | Erythromycin residue is equal to detection limit in sample |
| T line < C line or T line is invisible | Positive | Erythromycin residue is higher than detection limit in sample |
| C line is invisible | Invalid | The test strip is invalid, test again |
8. Precautions
1) The test strip is used for once at room temperature, do not use
test strip out of date.
2) 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.
3) Do not touch the white membrane surface in the middle of test
strip, avoid sunlight and fan blowing directly.
4) Milk samples should be fully liquid without any agglomeration,
sour and precipitation
5) Use the test strips testing again for positive results.
9. Specificity

tetracyclines, etc.
