Effect of N-terminal tags on A23187-stimulated [3H]arachidonic acid release from Spodoptera frugiperda (Sf9) cells expressing cPLA2γ. [3H]arachidonic acid-labeled Sf9 cells expressing cPLA2γ (circles), 6× histidine-tagged cPLA2γ (diamonds), GFP-cPLA2γ (triangles), or empty vector (squares) were treated with either vehicle (DMSO; open symbols) or 2 μg/ml A23187 (closed symbols) for the times shown. The amount of [3H]arachidonic acid released into the medium is expressed as a percentage of the total incorporated radioactivity. Data shown are averages ± SD of triplicate samples of one experiment that is representative of three independent experiments.
