Abcam's Free Fatty Acid Quantification Assay Kit provides a convenient, sensitive enzyme-based method for detecting the long-chain free fatty acids (FA) in various biological samples, such as serum, plasma and other body fluids, food, growth media, etc. In this assay, FA are converted to their CoA derivatives (coenzyme A), which are subsequently oxidized, leading to formation of color/ fluorescence. Fatty acids can then be easily quantified by either colorimetric (spectrophotometry at λ= 570 nm) or fluorometric (at Ex/Em= 535/587 nm)
