Catalogue No.: LSY-20095
1. Brief
The Beta-Lactams and Cephalexin Combo rapid test strip, based on Colloidal gold immunochromatography assay method, is used for testing β-lactam antibiotics and Cephalexin residue 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 β-lactam and Cephalexin 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.
