Effect of PEG–potassium phosphate systems’ variables on the recovery of MPs and PLA2. A Principal component analysis (PCA) of the recovery of MPs and PLA2 in systems with a PEG molecular weight of 400, 1000 and 3350 g mol−1, TLL 15, 25, 35 and 45% w/w and VR 0.33, 1 and 3. Clear circles (○) denote the selected systems with the best partition characteristics. B SDS-PAGE of 15 μg of C. m. nigrescens venom (CMNv) and molecular weight marker (MWM). C SDS-PAGE of top and bottom phases (T and B, respectively) of selected ATPS from PCA analysis
