BT Combo Strip Test Kit In Milk Samples

The assay uses a competitive colloidal gold based format. The milk sample (200 μL) is added to a clear plastic reaction vessel, and used to resuspend the lyophilized reagents to a uniform pink color in the bottom of the microtiter wells. The milk is incubated briefly (3 min) to allow the both antibiotic binding proteins on the gold particles to engage with any antibiotic present in the milk.

The test strip is then inserted into the sample well with the arrows pointing downward initiating capillary flow up the strip. Any gold particles that are not complexed with antibiotics present in the milk will bind to their respective test line, forming a signal (red line) at that position. Each test strip is imprinted with two test lines and one Control line (C -line). One test line allows for the detection of tetracyclines, and the other for the detection of beta -lactam antibiotics. If the binding protein on the gold particle has engaged with either a tetracycline or a beta-lactam antibiotic present in the milk sample, the gold particle will flow past the test line corresponding to that antibiotic and reach the C-line. For visual interpretation of the test results, any test line signal intensity that is stronger than the signal at the C -line indicates a negative

result. Signal at any test line which is equal or less intense compared to th e
