Effect of pH on the recovery of MPs and PLA2 in PEG–salt systems. A Principal component analysis (PCA) analysis of the recovery of MPs and PLA2 in selected systems at different pH values (7.5–10). Clear circles (○) denote the selected ATPS with the best partition characteristics. B Effect of pH on MPs and PLA2 activities. C SDS-PAGE of top and bottom phases (T and B, respectively) of selected ATPS from PCA analysis, 15 μg of C. m. nigrescens venom (CMNv) and molecular weight marker (MWM)
