Beta-lactams, Tetracyclines, Sulfonamides and Quinolones Combo rapid test strip
Catalogue No.: LSY-20104
1. Brief
The Beta-lactams, Tetracyclines, Sulfonamides and Quinolones Combo rapid test strip, based on Colloidal gold immunochromatography assay method, is used for testing Beta-lactams, Tetracyclines, Sulfonamides and Quinolones residues in milk and goat milk quickly.
 
2. Specifications
(1) 8 microwells and 8 dipsticks in one bottle      12 bottles / kit.
(2) Instruction                                        1 piece
 
3. Principle
The Beta-lactams, Tetracyclines, Sulfonamides and Quinolones Combo rapid test strip is based on competitive inhibition immuno-chromatographic principle. When the antibiotics residue in sample is higher than or equal to the detection limit, it will combine with labeled 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 antibiotics residue in sample, C line is visible.
 
4. Detection limit (See Tablet 1)
 
5. Operation procedures
1) Read the manual carefully before testing, return test strips and milk sample into room temperature before use.
2) Take bottles needed from the kit package, take out required microwells, making proper marks, Please use it in 1 hour. Seal the cap of the bottles, avoid moisture.
3) Use Micro-pipette to take 200ul of the samples into the microwells, then repeatedly absorb for 5 times, mix the sample with the reagent in the microwells completely until no solid judged by eyes (this is a very important step).
4) Incubate at (40±2???) for 5min, then insert the strip into micro-well, put the end with MAX down into the liquid.
5) Insert the strip into the liquid for 5min, then read the result.
 
6. Test Result Interpretation

Color depth comparison of  T line and C line
Result judgment
Result analysis
T line > C line
Negative
antibiotics residue is lower than detection limit in sample
T line = C line
Weak positive
antibiotics residue is equal to detection limit in sample
T line < C line or T line is invisible
Positive
antibiotics residue is higher than detection limit in sample
C line is invisible
Invalid
The test dipstick is invalid, test again

4) Do not touch the white membrane surface in the middle of test dipsticks, avoid sunlight and fan blowing directly.
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.
