The combined effect of bovine serum albumin alone and albumin with 60 nm PS-COOH on MPO activity.

MPO was mixed with different concentrations of BSA and thereafter with 60 nm PS-COOH before the MPO activity is measured. The results are reported as % of MPO activity in samples without added BSA or nanoparticles. All activities in presence of NPs with or without added BSA are significantly different from activity without BSA (p<0.05).
