  • Product overview

    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.


    In the free fatty acid assay protocol, fatty acids 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 (λ= 570 nm) or fluorometric (Ex/Em= 535/587 nm) methods. Palmitic acid is used to generate a standard curve.


    Free fatty acid assay protocol summary:
    - add samples and standards to wells
    - add reaction mix and incubate for 30 min at 37ºC
    - analyze with microplate reader


    Chinese protocol available. See protocols section below.

  • Notes

    Previously called Free Fatty Acid Quantification Assay Kit.

    This assay detects C-8 (octanoate) and longer fatty acids.

    Fatty acids are carboxylic acids with long hydrocarbon chains. The hydrocarbon chain length may vary from 8-30 carbons. Fatty acids play very important roles in normal metabolism and many disease development. They are precursors to a number of bioactive classes of compounds such as prostaglandins, leucotrienes and others, and have been implicated in diverse functions such as autism, immune system and inflammation response.
