In vitro pulldown assays for interactions between the three characterized ycf3-intron 2 splicing factors. (A) SDS-PAGE showing elution of His-THA8 from a gel filtration column. (B) Equal amounts of MBP-APO1, Strep-OTP51, and His-THA8 were combined (input), and then subjected to affinity chromatography on either NiNTA or amylose-coupled agarose beads. Each protein alone was also incubated with the beads to assess nonspecific interactions. Equal proportions of material eluted from the washed beads (pellet) and the corresponding supernatants (sup) are shown.
