(a) SDS-PAGE of target protein purification by reaction of target protein-ELP and SrtA-ELP fusions. Left to right for each target protein: reaction product, centrifugation pellet, and centrifugation supernatant. (B) SDS-PAGE of ternary fusion reactions. Left to right for each target protein: unreacted ternary fusion, reaction product, centrifugation pellet, and centrifugation supernatant.
