The β-lactam antibiotics rapid test dipstick is based on competitive inhibition immuno-chromatographic principle. When theβ-lactam antibiotics residue in sample is higher than or equal to the detection limit, it will combine with labled 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 isβ-lactam antibiotics residue in sample, C line is visible. Introduction β-lactam antibiotics Rapid test strip 1. Brief Theβ-lactam antibiotics Rapid test strip, based on Colloidal gold immunochromatography assay method, is used for testing β-lactam antibiotics residue in milk and goat milk. 3.Principle The β-lactam antibiotics rapid test dipstick is based on competitive inhibition immuno-chromatographic principle. When theβ-lactam antibiotics residue in sample is higher than or equal to the detection limit, it will combine with labled 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 isβ-lactam antibiotics residue in sample, C line is visible. 5.Operation procedures 1) Read the manual carefully before testing, return test dipsticks 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.
