overview

Benzoic acid (BA) rapid detection test strips have the characteristics of convenience, speed, and sensitivity, and are suitable for on-site large-scale sample detection. The test strip contains antigens pre fixed in the nitrocellulose membrane testing area (T) and II antibodies in the control area (C). After dissolving the gold labeled antibody in the micropores with milk sample, incubate at 50 ℃ for 3 minutes, insert the test strip into the gold labeled micropores and react for 5 minutes. Compare the color intensity of the T and C zones to determine the results. Regardless of the presence or absence of benzoic acid in the sample, a purple red band will appear in the C region.
