LabAssay™ Ammonia
Ammonia is mainly produced in the intestine or the kidney. Ammonia produced in the body is converted to urea through a series of reactions known as the urea cycle in the liver and eliminated through urine.
※For research purposes only with animal serum/plasma, Not for Diagnostic Use
Assay Principle (Modified Fujii-Okuda Method)
Ammonia is converted to Dioxydiphenylamine by the reaction of Phenol and Sodium Pentacyanonitrosyl ferrate(III). A reaction of the Dioxydiphenylamine with Sodium Hypochlorite produces Indophenol ,which pigments blue, under alkaline conditions. LabAssay™ Ammonia is a kit used for the quantitative determination of ammonia nitrogen in samples by measuring absorbance of the blue color.

LabAssay™ NEFA
NEFA (Non‐esterified fatty acid) in the blood is transported complexed with an albumin to peripheral tissues. They are important sources of fuel for the peripheral tissues. The concentration of NEFA in the blood is regulated by a release from the adipose tissues, a consumption in the periphral tissues or a take up from the liver.
※For research purposes only with animal serum/plasma, Not for Diagnostic Use
Assay Principle (ACS・ACOD method)
NEFA (Non‐esterified fatty acid) forms Acyl-CoA in the presence of Acyl-CoA synthetase (ACS). Hydrogen peroxide, which is produced by a reaction between the Acyl-CoA and Acyl-CoA oxidase (ACOD), promotes oxidative condensation of 3-methyl-N-ethyl-N-(β-hydroxyethyl)-aniline (MEHA) with 4-aminoantipyrine. LabAssay™ NEFA can be used for the quantitative determination of NEFA in samples by measuring absorbance of a blue purple color which is generated by the oxidative condensation reaction.

LabAssay™ Triglyceride
Triglycerides are neutral fats consisting of three fatty acids esterified to a glycerol backbone. There are triglycerides, cholesterol, phospholipids, free fatty acids and fat-soluble vitamins as lipid-soluble substances in the blood.
※For research purposes only with animal serum/plasma, Not for Diagnostic Use
Assay Principle
Triglycerides are converted to glycerol-3-phosphate by lipoprotein lipase and glycerolkinase. Hydrogen peroxide, which is produced by a reaction between the glycerol-3-phosphate and glycerol-3-phosphate oxidase(GPO), promotes oxidative condensation of N-ethyl-N-（2-hydroxy-3-sulfopropyl）-3,5-dimethoxyaniline sodium salt(DAOS) with 4-aminoantipyrine. LabAssay ™ Triglyceride can be used to detect triglycerides concentration in samples by measuring absorbance of a blue color which is generated by the oxidative condensation reaction.
