overview

The sulfonamides (SAS) rapid detection test strip has the characteristics of convenience, speed, and sensitivity, and is 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. If the sample is negative, a purple red band will appear in the T zone after adding the sample; If the sample is positive, there will be no purple red band in the T zone. Regardless of the presence or absence of sulfonamides in the sample, a purple red band will appear in the C region.
