Chloramphenicol CAP Rapid Test Strip for Milk 96 Tests/Kit 0.07 ~ 0.1 ppb
1. Specifications:
8 dipsticks/bottle, 12 bottles/box
2. Chloramphenicol Rapid Test Strip Brief
This product is used for testing Chloramphenicol in milk sample
(pure milk and fresh milk) and goat’s milk sample qualitatively.
The whole test procedure only need 13min, easy to operate with high
sensitivity.
3. Detection limit [ppb (ug/kg)]
Milk: 0.07-0.1ppb
4. Chloramphenicol Rapid Test Strip Contents
CAP test dipsticks | 8 dipsticks/bottle |
Red powder micro-wells | 8 micro-wells/bottle |
Manual | 1 piece |
Desiccant | 2 pieces/bottle |
5. Principle
The Chloramphenicol rapid test dipstick is based on competitive
inhibition immuno-chromatographic principle. In the flow process,
Chloramphenicol in the sample combined with Chloramphenicol
specific colloidal gold-labeled monoclonal antibody, Inhibit the
combination between antibody and Chloramphenicol-BSA conjugate on
Test line of NC membrane, lead to the color change of Test line.
When the sample has no Chloramphenicol residue or concentration
lower than detection limit, T line is darker than C line.When the
concentration is equal to or higher than detection limit, T line is
obviously lighter than C line or T line has no color or T line has
same color with C line. No matter whether there is Chloramphenicol
residue in sample, C line will appear, it means the test is valid.
6. Operation process
6.1 Please read the manual carefully before use. Return the test
dipstick and sample to room temperature.
6.2 Take the required bottles from the kit, take out the required
micropores and dipsticks, and mark them appropriately. Please use
these test strips within 1 hour. Seal the cap to avoid moisture.
6.3 Take 200ul of the sample to be tested in the microwell, absorb
it 5 times, and mix the sample with the reagent in the microwell
until it is judged by the naked eye that there is no solid (this is
a very important step).
6.4 (40±2℃) incubate for 3min, insert the test paper into the
microwell, and completely immerse the “MAX” end into the mixed
solution.
6.5 Insert the test strip into the microwell for 10 minutes to read
the result, other time is invalid.
7. Test Result Interpretation
Color depth comparison of T line and C line | Result judgment | Result analysis |
T line > C line | Negative | Chloramphenicol residue is lower than detection limit in sample |
T line = C line | Weak positive | Chloramphenicol residue is equal to detection limit in sample |
T line < C line or T line is invisible | Positive | Chloramphenicol residue is higher than detection limit in sample |
C line is invisible | Invalid | The test dipstick is invalid, test again |
8. Matters needing attention
1) The test strip can only be used once at room temperature, do not
use expired test strips.
2) After taking out the required test strips, please seal the
bottle. If you cannot use all 8 microwells at once, return the
remaining cups to the bottle and seal.
3) Do not touch the white film surface in the middle of the test
card, avoid direct sunlight and direct fan blowing.
4) The milk sample should be completely liquid without any clumping
and sedimentation.
5) Use the test strip again for a positive result.
9. Specificity
Tests 500ppb sulfonamides, quinolones and tetracyclines. All
results were negative.
