Biochim Biophys Acta . 1988 Jan; 958(1):116-24. PMID: 3334860
The susceptibility of partially peroxidized liposomes of 2-[1-14C] linoleoylphosphatidylethanolamine ([14C]PE) to hydrolysis by cellular phospholipases was examined. [14C]PE was peroxidized by exposure to air at 37 degrees C, resulting in...

Biochim Biophys Acta . 1986 Jun; 858(1):217-20. PMID: 3754767
Using [1-14C]oleate-labelled autoclaved Escherichia coli as substrate, we demonstrate that many, but not all, commercial preparations of xanthine oxidase contain phospholipase A2 activity as a contaminant. Phospholipase A2 activity (64.3-545.6...
