Sulfonamide Rapid Test Strip

Brand: FSTest
CatNO: DP32.4601.5
Specifications: 96 tests/kit
Shelf life: 12 months
Application: Intended to test Sulfonamide residues in raw milk, pasteurized milk and other samples.

Principle
The FSTest Sulfonamide Rapid Test Strip is based on immunochromatographic assay. The test strip has an area for result reading, which has a T (Test) line and C (Control) line. Both lines are invisible before testing. When the sample is applied to the loading side of the strip, the liquid will laterally flow upward through the surface of the test strip and react with the pre-coated recombinant antigens. If there are Sulfonamide in the sample, the intensity of T line will be inhibited and become relatively lighter than C line. Meanwhile the C line should always appear after a sample is applied, which indicates a valid result. By this means, the device can indicate the presence of Sulfonamide in the sample.

Procedure & Steps

1. Before use, ensure the milk sample and the test strips are between 20 to 40°C. 
   Note: Make sure the milk sample is homogenous, refrain from using
   samples with clumps, a murky appearance, odd scents or other sensory anomalies. 
   
2. Open the package tube, take out the test strips and microwells and make necessary labels or markings. 
   Note: Re-cap the tube immediately after usage to avoid
   contamination and moisture. 
   
3. Pipette 200 μL of sample into the microwells (which contain lyophilized reagent), mix slowly but thoroughly with pipette, then incubate for 3 mins at room temperature (20-40°C)
   
4. Insert the test strips into the microwells and start timing.
   
5. Interpreted results in 8-10 mins. Results are invalidafter10mins.
