3 Principle
The deoxynivalenol in the sample extract reacts with the colloidal gold particles in the test strip, and the color depth is deoxidized in the sample.
The content of snow rot fungi is related. Use a reader to determine the color depth of the test strip, based on the color depth and the built-in curve of the reader
The content of deoxynivalenol in the sample was calculated.
4 reagents
Unless otherwise stated, the reagents used are of analytical grade, and laboratory water should meet the requirements of Class III water in GB/T 6682.
4.1 Dilution Buffer. Provided by a colloidal gold test strip or prepared according to its instructions.
4.2 Extract. Water or extract matching the colloidal gold test strip.
5 equipment materials
