Food Safety Test Strip

The Beta-Lactams and Tetracyclines Combo rapid test strip, based on Colloidal gold immunochromatography assay method, is used for testing β-lactam antibiotics and Tetracyclines residue in milk and goat milk quickly.

2. Specification

(1) 8 microwells and 8 dipsticks in one bottle 12 bottles / kit.

(2) Instruction 1 piece

3.Principle

The β-lactam and Tetracyclines 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.

5.Operation procedures

1) Read the manual carefully before testing, return test strips and milk sample into room temperature before use.

2) Absorb 200ul milk sample into Micro-well, sucking 5~10 times until sample mix even with reagent in micro-well, observe by eyes no solid.

3) Incubate at 40℃for first step[Recommended, if no incubator, incubate at room temperature(25℃) is also OK], timing for 5min;

4) Insert the strip into micro-well, put the end with MAX down, incubate at 40℃ for second step[Recommended, if no incubator, incubate at room temperature(25℃) is also OK], timing for 5min

5) Take out the strip from micro-well, judge the result.
