β-lactamase rapid test strip
Catalogue No.: LSY-20045
1. Brief
The β-lactamase rapid test strip, based on Colloidal gold immunochromatography assay method, is used for testing β-lactamase residue in milk and goat milk.
2. Specifications
(1) 8 white microwells, 8 red microwells and 8 dipsticks in one bottle 12 bottles / kit.
(2) Instruction 1 piece
3. Principle
The β-lactamase rapid test dipstick is based on competitive inhibition immuno-chromatographic principle. When the β-lactamase residue in sample is higher than or equal to the detection limit, it will degrade the standard in white microwells, make labeled antibody combine with coated antigen on T line, making T line is darker than C line or has same color with C line; Otherwise, When the β-lactamase residue in sample is lower than the detection limit, the standard in white microwells will compete combination of labeled antibody. Making T line lighter than C line or T line invisible. Otherwise, . No matter whether there is β-lactamase residue in sample, C line is visible.
4. Detection limit
Detection Limit | 2 U/ml | 0.75 U/ml |
Test method | First-step incubation for 9min | First-step incubation for 16min |
5. Storage and expiry date
