Free Fatty Acid Assay Kit ab65341 uses a convenient,
sensitive enzyme-based method for detecting long-chain free fatty acids in
various mammalian and other samples, such as serum, plasma and other body
fluids, food, growth media, etc.
Other names used to refer to this type of assay include NEFA
assay and FFA assay.
How the assay works
Free Fatty Acid Assay kit ab65341 measures non-esterified free fatty acids;
specifically C-8 (octanoate) and longer fatty acids.
In the free fatty acid assay protocol, free fatty acids are
converted to their coenzyme A derivatives by Acyl-CoA Synthetase. These are
then oxidized by Acyl CoA Oxidase in a reaction that produces hydrogen
peroxide. Hydrogen peroxide is then processed by an enzyme causing a reaction
with a probe to generate red color (λmax = 570 nm) and fluorescence (Ex/Em =
535/587 nm). Palmitic acid is used to generate a standard curve.
The free fatty acid assay method using Acyl-CoA Synthetase
and Acyl CoA Oxidase as used in ab65341 is the standard method used for free
fatty acid assays.
