Anti-Glyphosate

• Background:

  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) .

• HS Code:

  38221900

• Host:

  Chicken

• Immunogen:

  BSA-conjugated Glyphosate (coupled via EDAC/NHS), Target: Glyphosate, CAS no, : 1071-83-6 from SIGMA

• Clonality:

  Polyclonal

• Applications:

  ELISA (ELISA), Immunoaffinity chromatography (IAC)

• Field of Research:

  Other compounds

• Dilution:

  1 : 2000 (ELISA)

• Purity:

  Total IgY. Purified by PEG precipitation.

• Format:

  Liquid

• Precautions:

  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.

• Additionnal Information:

  Antibody is provided in 0.01M PBS, pH 7.2. Composition of PBS: 8 mM Na2HPO4; 2 mM KH2PO4, 137 mM NaCl; 2.68 mM KCl. pH 7.4For coating OVA-glyphosate or KLH-glyphosate can be used.

• Storage Conditions:

  Store at 4°C up to one month or in aliquots at -20°C for long time storage. Avoid repeated freezing and thawing. For long term storage purposes in solution the addition of sodium azide at 0.02 % is advised with the appropriate precautions of use.
