Figure Lengend Snippet: (A) SDS-PAGE of POPs samples from affinity chromatography experiments: 1= Protein MW ladder (kDa), 2= Trypanosoma cruzi POP ( Tc POP), 3= Trypanosoma brucei POP ( Tb POP), 4= Leishmania major POP ( Li POP) and Homo sapiens POP ( Hu POP). SEC-MALS experiments, using a S200 10/300 confirmed the theoretical molecular mass values for each POP (B-E) of ∼ 78 kDa, corresponding to ∼ 13 mL elution volume.
Article Snippet: Finally, the proteins were concentrated using 30kDa MWCO Amicon (Millipore) ultra-centrifugal filters to 10 mg/mL and immediately injected in gel filtration column S200 10/300 (Cytiva) equilibrated with 20mM Hepes and 150mM NaCl at pH 7.4.
