BSA-conjugated Glyphosate (coupled via EDAC/NHS) , Target: Glyphosate, CAS no.: 1071-83-6 from SIGMA.
For coating OVA-glyphosate or KLH-glyphosate can be used.
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 μg/l, while the end concentration is 100 μg/l. The standard curve runs from 5 – 100 μg/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.
Glyphosate (N-(phosphonomethyl)glycine) is a herbicide of a broad action spectrum which is used to kill broadleaf weeds and grasses known to compete with commercial crops world-wide. Due to its physico-chemical properties glyphosate easily enters the aqueous environment where it is rapidly converted into its main metabolite AMPA (aminomethylphosphonic acid).
