  • 产品概述

    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 (spectrophotometry at λ= 570 nm) or fluorometric (at Ex/Em= 535/587 nm).

  • 说明

    Previously called Free Fatty Acid Quantification Assay Kit.

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

  • Lipolysis were evaluated by measuring free fatty acids released into the culture medium of siCreg1 or si-Scramble 3T3-L1 cells using ab65341, which were treated with BMS-345541 (5 µmol/L), an NF-?B pathway inhibitor, or vehicle (DMSO) for 48 hours prior to lipolysis assessment. ns, no significance; and ***P<0.001.

  • Plasma FFA levels was measured using ab65341 in male and female wild-type (WT) or AT2KO mice either on normal diet (ND) or high fat diet (HFD).

  • Colorimetric standard curve: mean of duplicates (+/-SD) with background readings subtracted.

  • Free Fatty Acid measured in biologicals showing concentration (µM)

  • Flourometric standard curve: mean of duplicates (+/-SD) with background readings subtracted.

Plasma from yellow-bellied marmots (Marmota flaviventris) was processed according the protocol. A serial dilution of the plasma (shown) was compared to the standard curved (also shown) to determine the optimal dilution factor for subsequent assays.
