Streptomycin Gentamicin and Kanamycin Combo Rapid Test Strip 96 Tests/Kit
1. Specifications
8 strips/bottle, 12 bottles/kit
2. Brief
The Streptomycin, Gentamicin and Kanamycin combo rapid test strip
is based on Colloidal gold immunochromatography, used for testing
Streptomycin, Gentamicin 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.
3. Detection limit:
Name | Detection limit (ppb) |
Streptomycin/dihydro streptomycin | 5-10/10-15 |
Gentamicin | 3-5 |
Kanamycin | 3-5 |
4. Contents
1 | Test strip | 8strip/bottle |
2 | Red powder micro-well | 8 micro-well/bottle |
3 | Desiccant | 2piece/bottle |
4 | Instruction | 1 piece |
5. Principle
The Streptomycin, Gentamicin and Kanamycin 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 5~10 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 5min.
6.5 Then insert the strip into micro-well, put the end with MAX
down into the liquid, Incubate at (40±2℃) for second step, timing
for 5min.
6.6 Take out the strip and read the result as the picture, it is
invalid to read result in other times.
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, goat milk and fresh
milk.
2) Use the test strip once at room temperature, do not use expired
test strips.
3) Cap the bottle immediately after removing the reagent. If the 8
microwells cannot be used at a time, immediately cap the
microwells, put them back in the bottle, and store them in an
airtight container.
4) Do not touch the white film surface in the middle of the test
paper, avoid direct sunlight and direct blowing by fans.
5) Store milk samples refrigerated for no more than 3 days.
6) The milk sample should be completely liquid without any lumps,
sourness and precipitation. The samples were mixed and stirred well
before testing.
7) For high-fat samples, the chromatography is slower, and it is
recommended to extend the second step by an additional 1 minute.
8) Use the test strip again for a positive result.
9. Specificity
This product has no cross-reaction with quinolones, sulfonamides,
melamine, etc.
