Food Safety and Nutrient Detection

The Triglyceride Quantification Kit provides a sensitive, easy assay to measure TG concentration in a variety of samples. In the assay, TG are converted to free fatty acids and glycerol. Theglycerol is then oxidized to generate a product which reacts with theprobe to generate color (spectrophotometry at λ = 570 nm) and fluorescence (Ex/Em = 535/587 nm). The kit can detect 2 pmol-10nmol (or 2-10000µM range) of triglyceride in various samples. The kit also detects monoglycerides and diglycerides.

Zinc Fluorometric Assay kit provides an easy and quantitative method to measure the metal ion Zinc in various biological samples. The assay is based on the ability of our proprietary probe that binds with high specificity to Zinc and becomes fluorescent. The fluorescent intensity is directly proportional to the amount of zinc, which can be quantified by measurement at Ex/Em= 435/535 nm in a microplate reader. This assay kit provides a just add-and-read, non-radioactive, and high-throughput adaptable for Zinc detection. The assay is rapid (less than 10 min) and sensitive (Limit of Detection: <0.1 µM)

Zinc Assay Kit is a convenient colorimetric assay in which Zinc binds to a ligand with development of absorbance at 560 nm. The assay can be used with biological samples such as serum, plasma, csf or urine with detection sensitivity 0.2 µg/ml (~1-3 µM).

β-lactamase Rapid Detection Kit is designed for the detection of β-lactamase in milk.

Tryptophan Assay Kit provides a simple, sensitive, and high-throughput adaptable assay that detects tryptophan concentration in biological fluids, including free and bound tryptophan in serum. The principle is based on the non-enzymatic reaction to generate a fluorophore (Ex/Em = 370/440 nm) using tryptophan as a building block. The reaction is specific and other amino acids do not interfere with the assay. The assay can detect as little as 2.5 µM of TRP in a variety of biological samples.

β-lactam antibiotics Rapid Detection Kit is designed for the detection of β-lactam antibiotics in milk.

Acetoacetate Assay Kit has adapted that principle with a modification that provides a sensitive method to quantitate endogenous levels of AcAc in human blood, and urine. In this non-enzymatic assay, AcAc reacts with a substrate to generate a colored product that can be measured at 550 nm. The reaction is specific for AcAc and does not detect 3-β-hydroxybutyrate. The assay kit can detect samples containing acetoacetate as low as 25 µM.

α-amylase Assay uses ethylidene-pNP-G7 as the substrate. Once the substrate has been specifically cleaved by α-amylase, the smaller fragments produced can be acted upon by α-glucosidase, which causes the ultimate release of the chromophore that can then be measured at 405 nm. The assay can detect α-amylase content as low as 0.2 mU.

Aspartate Assay Kit provides a simple, convenient assay to measure aspartate in a variety of samples. In the assay, aspartate is converted to pyruvate which is oxidized with the conversion of a probe into a highly colored (570 nm) and fluorescent (Ex/Em 535/587 nm) species proportional to the amount of aspartate in samples. Aspartate can be quantified in the range between 0.1–10 nmoles/well (2-200 µM).

Autophagy/Cytotoxicity Dual Staining Kit (Cell-Based) enables detection and monitoring of autophagy and autophagic cell death in cultured cells. The kit contains two fluorescent probes: a membrane permeable selective autophagy stain and a cell death marker. An autophagy-inducing positive control reagent, which increases autophagy staining and serves as an experimental control. This easy-to-use non-radioactive kit allows researchers to study the regulation of autophagy and cytotoxicity at the cellular level by Fluorescence Microscopy and Flow Cytometry in cultured cells.
