Reduced Glutathione Kit is based on an enzymatic cycling method in the presence of GSH and a chromophore. The reduction of the chromophore produces a stable product, which can be followed kinetically at 450 nm. Therefore, its absorbance is directly proportional to the amount of GSH in the sample. Our kit is the most specific and sensitive quantitative assay in the market because GSSG does not interfere with the assay. The kit includes 5-Sulfosalicylic acid (SSA) in order to protect samples’ GSH endogenous content. (SSA acts as a deproteinizing and antioxidant agent. The assay is simple, reproducible and can specifically detect as low as 50 pmol/well of reduced form of Glutathione (GSH) in a 100 µl reaction.

Sodium Assay Kit offers a simple, two-step colorimetric assay that is based on the requirement of sodium ion as a cofactor for the enzymatic activity of β-Galactosidase (βG). Endogenous mono-, di-, and trivalent ions, ascorbic acid, creatinine, glucose, urea, and bilirubin do not interfere with the assay. The kit can detect Sodium concentration as low as 25 µM in a variety of samples.

Taurine Assay Kit enables the measurement of Taurine level in both biological fluids as well as food products, such as energy drinks. The kit utilizes the ability of an enzyme to convert Taurine into aminoacetaldehyde and sulfite. The produced sulfite is measured using a probe which can be detected using a microplate reader (OD 415 nm). This assay kit is simple, high-throughput compatible and can detect as low as 5 nmols of Taurine.

This TAC Assay Kit can measure either the combination of both small molecule antioxidants and proteins or small molecules alone in the presence of our proprietary Protein Mask. Cu²ᶧ ion is converted to Cu+ by both small molecule and protein. The Protein Mask prevents Cu²ᶧ reduction by protein, enabling the analysis of only the small molecule antioxidants. The reduced Cu+ ion is chelated with a colorimetric probe giving a broad absorbance peak around 570 nm, proportional to the total antioxidant capacity.

In Total Carbohydrate Assay, polysaccharides (mono, di, tri, etc.) and their derivatives, in the presence of sulfuric acid, are hydrolyzed to monomers and converted to furfural or hydroxyfurfural, which react with the Developer to form a chromogen that can be quantified by measuring the absorbance at 490 nm. The Total Carbohydrate Assay can detect most forms of carbohydrates, including simple and complex saccharides, glycans, glycoproteins and glycolipids.

Total Sulfite Assay kit is a simple and sensitive assay to detect small concentrations of sulfites in a variety of food and beverage samples. This assay is based on the oxidation of sulfite to sulfate producing a stable signal at 570 nm, which is directly proportional to the amount of sulfite in the sample. This assay is very sensitive and can detect as low as 20 µM of sulfite in a variety of samples.

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)
