Product Description
Streptomycin & Lincomycin & Neomycin 3in1 Rapid Test
Rapid Test for the presence of Streptomycin + Lincomycin + Neomycin in raw cow milk, Pasteurized milk, UHT milk sample
PRINCIPLE
The DairyPal SLN is competitive test involving three receptors in one single operation, the Streptomycin and Lincomycin and Neomycin in the milk sample compete for the antibody with the antigen coated on the membrane of the test dipstick. Then after a color reaction, when the sample is free of the analytes, a strong colour density development occurs at the specific capture lines, indicating the presence of the concerned analytes in the milk sample. On the contrary, the presence of the analytes in the sample will not cause the strong coloured signal at the specific capture lines.
The DairyPal SLN is a rapid test that detect simultaneously the presence of either Streptomycin and Lincomycin and Neomycin molecules in raw cow milk, Pasteurized milk, UHT milk sample.
LIMIT OF DETECTION (LOD)
Streptomycin: 10-15 μg/L(ppb)
Dihydrostreptomycin: 10-15 μg/L(ppb)
Lincomycin: 20 μg/L(ppb)
Neomycin: 10μg/L(ppb)
Dihydrostreptomycin: 10-15 μg/L(ppb)
Lincomycin: 20 μg/L(ppb)
Neomycin: 10μg/L(ppb)
2. Take the kit out of the fridge and wait until the temperature of the reagents reaches the ambient temperature.
3. Calculate how many milk sample will be tested and mark the sample tubes to identify. The milk samples should be fully liquid without any clots or deposition, the ideal temperature of milk sample is between 4 to 20℃.
4. Take the tubes required from the kit package, take out as many micro-wells and dipsticks as the milk samples to be tested, and make proper marks to match the milk sample.
To open a dipsticks tube, press the safety ring down, take off the ring and get the tube cap off with your thumb.
Recover the cap tightly after taking out the required micro-wells and dipsticks.
Empty one test tube then open another one.
Keep the unused micro-well caps tightly sealed. Do NOT tear off the strip of 8 microwell caps.
Use the exposed dipsticks in 1 hour.
5. Preheat the Dry Incubator(suggest to use DairyPal Mini-B Dry Incubator) to 35℃.
6. Place the required numbers of the mircrowells in the dry incubator, transfer 200ul of the milk samples into the microwells, inject and reject the milk sample for 5 times consecutively to homogenize the lyophilized reagent and milk sample. Start the timer.
Dip the end of the plastic pipette(DairyPal Mini pipette) tips into the milk and slowly releases the sucker. When the sucker is back into its initial position, transfer the 200 µl of milk into the reagents, by slowly pushing the sucker down to the bottom.
7. Start the timer to incubate for 5 minutes at 35℃;
During the incubation, The receptors will detect the presence of the antibiotics in the milk sample. The reaction will take 5 minutes.
8. Dip the dipsticks into the micro-wells with the "Sample End" down side to the bottom.
9. Start the timer to incubate for 5 minutes again at 35℃.
10. Then take out the dipsticks and place them laterally in a dry clean place, peel off the sample pad, interpret the result.
Use a clean nipper(or new pipette tip) to scrape gently and slowly the sample pad.
The peeling off of the sample pad will stop the ongoing reaction of the receptors.
File the used sample pad peeled off dipsticks if necessary.

Visual Interpretation
The dipsticks are embodied with 4 lines, Control line, Streptomycin line, Lincomycines line and Neomycin line, and which are briefly expressed as “CTL”, “S”, “L” and “N”. The test results will be determined by the color presence of the lines. The following diagram describes the result identification.
NEGATIVE: CTL line, S Line, L Line and N Line are all red, Color of S line, L line, N Line are all stronger or similar than the CTL line, which means that, the milk sample contains fewer antibiotics than value given in the table.
Streptomycin POSITIVE: Line CTL is visible, Line S is weaker than Line CTL, Line L and Line N both are stronger than Line CTL, which means that the milk sample contains the Streptomycin more than the value in the table, the Lincomycin and Neomycin fewer that the value in the table.
Lincomycin POSITIVE: Line CTL is Visible, Line L is weaker than Line CTL, Line S and Line N both are stronger than Line CTL; which means that the milk sample contains the Lincomycin more than the value in the table, the Streptomycin and Neomycin fewer that the value in the table.
Neomycin POSITIVE: Line CTL is Visible, Line N is weaker than Line CTL,
Line S and Line L both are stronger than Line CTL; which means that the milk sample contains the Neomycin more than the value in the table, the Streptomycin and Lincomycin fewer that the value in the table.
Full POSITIVE: Line CTL is visible; either Line S, Line L or Line N is weaker than Line CTL; which means that, the milk sample contains the the Streptomycin, Lincomycin and Neomycin all more than the value in the table.
Remarks: Control line is used as a quality indicator, which will always appear regardless of the line S/L/N. If Control line does NOT appear, it indicates that the result is invalid. Users please check the kit insert again and re-do the assay with new test dipsticks.
Interpret the result with the DairyPal Test Dipstick Reader (TSR-100) according the user manual.
2-8℃ in cool dark place, do not freeze. The kit will be valid in 12 months. The lot number and expired date are printed on the package.
Do the assay following the instruction, do NOT touch the membrane of the dipstick.
Seal the bottle after taking out required dipsticks.
The dipstick is used for only once; Do NOT use it repeatedly.
The positive result should be further confirmed.
