| cytotoxic activities of [ser⁴⁹]phospholipase a₂ from the venom of the saw-scaled vipers echis ocellatus, echis pyramidum leakeyi, echis carinatus sochureki, and echis coloratus. | fractionation by reversed-phase hplc of venom from four species of saw-scaled viper: echis ocellatus, echis pyramidum leakeyi, echis carinatus sochureki, and echis coloratus led to identification in each sample of an abundant protein with cytotoxic activity against human non-small cell lung adenocarcinoma a549 cells. the active component in each case was identified by maldi-tof mass fingerprinting of tryptic digests as [ser⁴⁹]phospholipase a₂ ([ser⁴⁹]pla₂). an isoform of [ser⁴⁹]pla₂ containing t ... | 2013 | 23747272 |
