Penicillin Rapid Test Strip for Fresh Milk 96 Tests/Kit 2 ~ 4 ppb
1. Penicillin Rapid Test Strip Brief
The Penicillin rapid test strip, based on Colloidal gold
immunochromatography assay method, is used for testing Penicillin
residue in milk and goat milk.
2. Penicillin Rapid Test Strip Specifications
(1) 8 microwells and 8 dipsticks in one bottle 12 bottles / kit.
(2) Instruction 1 piece
3. Milk Test Kit Principle
The Penicillin rapid test dipstick is based on competitive
inhibition immuno-chromatographic principle. When the Penicillin
residue in sample is higher than or equal to the detection limit,
it will combine with labled antibody, then inhibit the combination
between colloidal gold antibody coated antigen on T line, making T
line lighter than C line or T line invisible or T line has same
color with C line. Otherwise, T line is darker than C line. No
matter whether there is Penicillin residue in sample, C line is
visible.
4. Detection limit: 2-4ppb
5. Milk Test Kit Operation procedures
1) Read the manual carefully before testing, return test dipsticks
and milk sample into room temperature before use.
2) Absorb 200ul milk sample into Micro-well, sucking 5~10 times
until sample mix even with reagent in micro-well, observe by eyes
no solid.
3) Incubate at 40℃for first step[Recommended, if no incubator,
incubate at room temperature(25℃) is also OK], timing for 3min;
4) Insert the dipstick into micro-well, put the end with MAX down,
incubate at 40℃ for second step[Recommended, if no incubator,
incubate at room temperature(25℃) is also OK], timing for 3min
5) Take out the dipstick from micro-well, judge the result.
6. Test Result Interpretation
Color depth comparison of T line and C line | Result judgment | Result analysis |
T line > C line | Negative | Penicillin residue is lower than detection limit in sample |
T line = C line | Weak positive | Penicillinresidue is equal to detection limit in sample |
T line < C line or T line is invisible | Positive | Penicillin residue is higher than detection limit in sample |
C line is invisible | Invalid | The test dipstick is invalid, test again |

8. Precautions
1) This product is suitable for pure milk of cattle and sheep and
raw milk.
2) Test dipsticks and micro-wells are disposable,do not use test

5) Store milk sample in cold, no more than 3 days.
6) Milk samples should be fully liquid without any agglomeration,
sour and precipitation. Stir milk sample to even before test.
7) For milk sample with high fat content, chromatography is slow,
recommending extension the second step for another 1 min.
8) Use the test dipsticks testing again for positive results.
