Figure 5.
SDS-PAGE analysis in non-reducing (A) and reducing (B) conditions of the consecutive SEC-MALS oligomer fractions with the elution time range of 22–32 min. An amount of 10 µg was loaded into each well. The average mass distribution over the analyzed fractions in the non-reducing conditions is inversely proportional to the SEC-MALS elution time, as expected. The higher the molecular weights, the more unstable the cytotoxin. The oligomeric fractions additionally contain monomer, dimer, and aggregates. The efficient oligomers monomerization was observed in the reducing conditions.
