The Screen-Well™ Fatty Acid Library contains 68 fatty acids of varying saturation and chain length. Many free fatty acids and their metabolites serve as precursors to important signaling systems (e.g. prostaglandins), act directly as receptor ligands or enzyme inhibitors, and have pro- or anti-atherosclerotic and anti-hypertensive properties through mechanisms that are still being characterized. Therefore, a diverse set of fatty acids can be a rich source of compounds for receptor de-orphaning, inhibitor screening, and high content screening. Fatty acids are supplied dissolved in DMSO at 10 mM and aliquoted into deep-well plates at either 100 or 500 µl per well. This set contains both fatty acids with defined activities and fatty acids with putative biological activities.Library includes:Unsaturated & saturated fatty acids, Arachidonic acid, C10-24 chain length Linolenic acid, E and Z isomers, γ-Linolenic acid and many more.
