Beta-lactam Antibiotics Rapid Test Strip

Principle

The β-lactam antibiotics rapid test dipstick is based on competitive inhibition immuno-chromatographic principle. When the β-lactam 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. Otherwise, T line is darker than C line or has same color with C line. No matter whether there is β-lactam antibiotics residue in sample, C line is visible.
