title: Filtration assay for arachidonic acid release.
abstract: Arachidonic acid (AA) release is a central message in cell signaling. Fatty acid release is generally assessed by manual sampling of radioactivity release from cells prelabeled with a radiolabeled fatty acid. The assay is laborious, time-consuming, and susceptible to high noise. Here we present a fast and reproducible method for 96-well filter plates and cells in suspension, a method that is best suited for agonist concentration-response studies and, thus, for ligand screening. The method offers tremendous time and effort savings and enables execution of large experimental series previously unattainable for AA release studies.
