5. Principle

The Streptomycin rapid test dipstick is based on competitive inhibition immuno-chromatographic principle. In the flow process, Streptomycin in the sample combined with Streptomycin specific colloidal gold-labeled monoclonal antibody, Inhibit the combination between antibody and Streptomycin-BSA conjugate on Test line of NC membrane, lead to the color change of Test line. When the sample has no Streptomycin 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 Streptomycin 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 dipsticks and sample into room temperature.

6.2 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.

6.3 Take 200ul of the test samples into the micro-wells, then repeatedly absorb for 5 times, mix the sample with the reagent in the micro-wells completely until no solid judged by eyes (this is a very important step).

6.4 Incubate for 5min at (40±2℃), then insert the test dipsticks into the micro-wells with the "MAX" end fully dipped in to the mixture solution.

6.5 Insert the test dipsticks into micro-wells for 5min then read the result, it is invalid in other time.

8. 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 microwells 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 card, avoid sunlight and fan blowing directly.
