Melamine Rapid Test Strip
OVERVIEW
Brief:
This product is used for testing Melamine in milk sample(pure milk
and fresh milk) and goat’s milk qualitatively, the whole test
procedure only need 6min, easy to operate with high sensitivity.
Detection limit in milk [ppb(ug/kg)]: 10~15
Principle:
The Melamine rapid test dipstick is based on competitive inhibition
immuno-chromatographic principle. In the flow process, Melamine in
the sample combined with Melamine specific colloidal gold-labeled
monoclonal antibody, Inhibit the combination between antibody and
Melamine-BSA conjugate on Test line of NC membrane, lead to the
color change of Test line.
When the sample has no Melamine 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
lighter than C line obviously or T line is invisible or T line has
same color with C line. No matter whether there is Melamine residue
in sample, C line will appear, it means the test is valid.
FEATURES & BENEFITS
Operation procedures:
1 Read the instruction carefully before use. Return test dipsticks
and sample into room temperature.
2 Take bottles needed from the kit package, take out required
micro-wells and dipsticks, making proper marks. Please use these
test dipsticks within 1h. Seal the cap of the bottles, avoid
moisture.
3 Take 200ul of the test samples into the micro-wells, then
repeatedly absorb for many times, mix the sample with the reagent
in the micro-wells completely until no solid judge by eyes (this is
a very important step).
4 Incubate for 3min at (40±2℃), then insert the test dipsticks into
the micro-wells with the "MAX" end fully dipped in to the mixture
solution.
5 Insert the test dipsticks into the solution for 3min, read the
result, it is invalid in other time.
Test Result Interpretation:
| Color depth comparison of T line and C line | Result judgment | Result analysis |
| T line >C line | Negative | Melamine residue is lower than detection limit in sample |
| T line =C line | Weak positive | Melamine residue is equal to detection limit in sample |
| T line <C line or T line is invisible | Positive | Melamine residue is higher than detection limit in sample |
| C line is invisible | Invalid | The test dipstick is invalid, test again |

Precautions:
1) The test dipsticks can be used only once at room temperature, do
not use test dipsticks out of expiry date.
2) Please seal the bottle after taking out required test dipsticks.
If can not use all 8 micro-wells at once, cup the rest and put it
back to bottle and sealed.
3) Do not touch the white membrane surface in the middle of test
dipsticks, avoid sunlight and fan blowing directly.
4) Milk samples should be fully liquid without any agglomeration,
sour and precipitation.
5) Use the test dipsticks testing again for positive results.
6) Please contact the supplier for any questions.
7) The result is for reference only, for confirmation, please refer
to the relevant national standard method.
Specificity:
There is cross-reaction with Streptomycin, Sulfonamides,
Quinolones, Chloramphenicol etc.
