Food Safety and Nutrient Detection

Glyphosate, Aminomethylphosphonic Acid and Glufosinate Rapid Detection Kit is designed for the detection of glyphosate, aminomethylphosphonic acid and glufosinate residues in food.

Pesticide Residue Pretreatment Rapid Detection Kit is designed for the detection of pesticide residue in vegetables and fruits with non-pigment, low-pigment, low-fat and low-waxy.

Pesticide Residue Pretreatment Rapid Detection Kit (High-Pigment) is designed for the detection of pesticide residue in vegetables and fruits with high-pigment.

Pesticide Residue Pretreatment Rapid Detection Kit (High-Fat and Waxy) is designed for the detection of pesticide residue in vegetables and fruits with high-fat and waxy.

Pesticide Residue Pretreatment Rapid Detection Kit (High-Pigment, Fat and Waxy) is designed for the detection of pesticide residue in vegetables and fruits with high pigmwnt, fat and waxy.

Alanine Assay Kit provides a sensitive detection method of alanine. In the kit, alanine is converted to pyruvate which is specifically detected leading to proportional color (λ=570nm: 0-10 nmol) or fluorescence (Ex/Em 535/587nm: 0-1 nmol) development. Serum concentration: ~24-76 µg/ml (~3-9 nmol/10 µl).

This kit provides a rapid, simple, sensitive, and reliable assay suitable for research and high throughput assay of Ammonia. In the assay, Ammonia is converted to a product that reacts with the OxiRed probe to generate color (λmax = 570 nm) which can be easily quantified by plate reader. The kit can detect 1 nmol (~20 µM) of ammonia, much more sensitive than measuring NADPH based ammonia assay.

This kit provides a rapid, simple, sensitive, and reliable assay suitable for research and high throughput assay of Ammonia. In this non-enzymatic assay, ammonia is used to form indophenol, a highly colored product easily quantifiable by colorimetry (OD670 nm) using a plate reader. The kit can detect less than 1 nmol (~10 μM) ammonia using either a 96 well or 384 well microwell plate.

FRASC Assay Kit provides a rapid, simple, and sensitive means of detecting ascorbic acid in biological samples such as serum and other body fluids, tissue and cell extracts, growth media and food products. In this assay, Feᶟᶧ is reduced to Fe²ᶧ by any antioxidants present. The ferrous iron is chelated with a colorimetric probe to produce a product with a strong absorbance band which can be monitored between 545-600 nm. The addition of ascorbate oxidase to parallel samples removes any ascorbate present leaving a background value which is subtracted from the total to give ascorbate content. The assay can detect 0.2 to 20 nmol of ascorbic acid in various samples.

Ascorbic Acid Assay Kit provides a rapid, simple, and sensitive means of detecting ascorbic acid in various biological samples. In this assay, our proprietary catalyst oxidizes ascorbic acid to produce a product that interacts with the ascorbic acid probe, generating color and fluorescence. Ascorbic acid can be easily determined by either colorimetric (spectrophotometry at λ = 570 nm) or fluorometric (Ex/Em = 535/587 nm) methods. The assay can detect 0.01-10 nmol of ascorbic acid per assay in various samples.
