This antibody was used to prepare anti-glyphosate immunoaffinity column which showed to be very specific and retained glyphosate but not AMPA or glufosinate. Recover of glyphosate was ca. 100 %. The antibody is applicable for any type of (waste) water sample. The detection limit is 2,5 \x{03bc}g/l, while the end concentration is 100 \x{03bc}g/l. The standard curve runs from 5 \x{2013} 100 \x{03bc}g/l. For an optimal ELISA result it is crucial to use Greiner high affinity plates; As assay buffer 0,1M PBS, 1% BSA heat-treated, pH 7,4 is recommended.
