The original example, along with the conjugated antibody bound to the target analyte, migrates even more along the test strip into the discovery area. An affordable style is used for spotting analytes in which the analyte is too small for 2 antibodies to bind simultaneously, such as vitamins and also antibiotics. In an affordable assay, the examination line contains the target analyte particle (generally a protein-analyte facility). If the analyte is absent in the sample, the nanoparticle antibody conjugates will bind to the analyte at the examination line, resulting in high signal intensity. If the target analyte exists in the sample, the analyte will certainly bind to the antibodies on the nanoparticle surface area and also prevent the nanoparticle from binding to the test line.
