5ppb Pesticide Residue Testing Kit Nodularins DM Microcystin Elisa

         Microcystins/Nodularins-DM ELISA Test Kit In Water Samples

Product Description

 OP/Carbamate Test Kit is for the detection of a wide range of organophosphate (including thiophosphate), and carbamate pesticides in water, (drinking water, ground water, surface water and well water).

The unique features of the kit are:

• High sensitivity.
• High reproducibility..
• A quick assay(less than 2 hours regardless of number of samples).

Procedure Overview

The test is a qualitative, colorimetric assay (modification of the Ellman method) for the detection of organophosphates and carbamates, based on a modification of their inhibition of the enzyme Acetyl Cholinesterase (ACh-E). Ach-E hydrolyzes acetylthiocholine (ATC) which reacts with 5,5’-Dithio-bis(2-Nitrobenzoic Acid) [DTNB] to produce a yellow color which is read at 405 nm. If OP or Carbamate pesticides are present in a sample, they will inhibit ACh-E and therefore the color formation will be reduced or absent depending on their concentration. Detection limits of the various OP/C pesticides differ depending on their ability to inhibit the enzyme (refer to Sensitivity table). If it has been established that only a single OP/C is present, the test can be used in conjunction with

appropriate standards for quantitative testing.
