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.
