a hGX sPLA2 enzymatic activity measured with radiolabeled Escherichia coli membranes in supernatant and cell lysates of COS-7 cells transfected either with an empty vector or with vectors encoding the R38 or C38 proteins as described in “Materials and methods”. A representative experiment of at least three experiments with similar results is shown. b Concentration of hGX sPLA2 protein quantified in supernatant and cell lysates of COS-7 cells transfected either with an empty vector or with vectors encoding the R38 or C38 proteins using TR-FIA assay as described in “Materials and methods”. A representative experiment of at least three experiments with similar results is shown
