In vitro polymerization of actin in the presence of nuclear extract. Partially polymerized actin was incubated alone, in the presence of nuclear extract, or in the presence of BSA. After centrifugation, supernatant and pellet fractions were resolved by SDS-PAGE and visualized with Coomassie blue. Each reaction was performed in duplicate, and both samples were loaded onto the gel. S indicates the monomer population, whereas P indicates the polymerized population.
