RC Combo Strip Test Kit In Urine, Feed, Tissue And Other Samples

Product description

        RC Combo Strip Test is a qualitative and rapid lateral flow assay designed to detect both ractopamine and clenbuterol residues   used to detect clenbuterol hydrochloride (CLE), ractopamine (RAC), salbutamol (SAL) in urine, feed, tissue and other samples. This test is designed for rapid field use or reference lab settings.

The features of the kit are:

l Rapid strip test method – 10 minutes

l No sample preparation required

l High sensitivity

l High reproducibility

Mechanism of reaction

The assay uses a competitive colloidal gold based format. The swine urine sample (200 μL) is added to a clear plastic reaction vessel,The assay uses a competitive colloidal gold based format. The swine urine sample (200 μL) is added to a clear plastic reaction vessel. The test strip is then inserted into the sample well with the arrows pointing downward initiating capillary flow up the strip. Any colloidal gold particles that are not complexed with beta-agonists present in the swine urine 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 ractopamine, and the other for the detection of clenbuterol. If the binding protein on the gold particle has engaged with either ractopamine or clenbuterol present in the urine sample, the gold particle will flow past the test line corresponding to that beta-agonist 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 the C-line indicates the presence of the corresponding beta-agonist in the swine urine. The greater the reduction in signal intensity at the test line, the greater the concentration of ractopamine or clenbuterol present in the swine urine. The assay is also designed to simultaneously detect ractopamine and clenbuterol residues. Limits of detection for each beta-agonist are listed in Table 1.
