產品說明: 抗生素殘留 Veratox® brand of diagnostics from Neogen® are quantitative microwell enzyme-linked immunosorbent assay (ELISA) tests. By running multiple controls and establishing a standard curve through a reader, samples can be plotted against the curve to determine the concentration of analyte present.
Veratox diagnostics can be either sandwich or direct competitive, they may also be read at a 650 nm or 450 nm wavelength, depending on the specifics of the kit. These kits are often viewed as the gold standard by the food industry, particularly in allergen and mycotoxin testing.
Each test kit contains antibody-coated microwells with antibodies specific to the kit’s target substance.
First, samples and controls are added to their respective test wells. Next, an enzyme conjugate (target substance chemically linked with an enzyme) is added. The samples/controls and conjugate are mixed and transferred to antibody wells where they compete for the antibody binding sites. The more target substance in the sample, the less conjugate that binds in the wells.
After an incubation, the wells are washed to remove all unbound materials.
A substrate, which changes color in the presence of the conjugate, is added to the wells. During an incubation, yellow color develops in proportion to the amount of conjugate versus target substance in the wells. The more conjugate bound, the more yellow color that develops, indicating less substance present.
Results are obtained by measuring the wells’ color change in a microwell reader and comparing the readings against a standard curve.
Veratox® for Chloramphenicol is used for the quantitative analysis of chloramphenicol residues in shrimp.
The test is a competitive direct ELISA that provides exact concentrations in parts per trillion (ppt). Free chloramphenicol in the sample and controls competes with enzyme-labeled chloramphenicol (conjugate) for the antibody binding sites. After a wash step, substrate reacts with the bound enzyme conjugate to produce blue color. A microwell reader is used to yield optical densities. Control optical densities form a standard curve, and sample optical densities are plotted against the curve to calculate the exact concentration of chloramphenicol.
