Figure 6From: Automated seamless DNA co-transformation cloning with direct expression vectors applying positive or negative insert selectionSmall scale purification of expression products. The cells of 4 ml culture were pelleted and disrupted by sonification. After centrifugation the target proteins in the supernatant were purified by automated batch IMAC and run on 12% SDS-PAGE. In each panel, total protein T, protein in the supernatant S and purified protein P are given. Typical examples of purifications are shown.Back to article page
