Gel-electrophoretic analysis of protein samples from different stages of the process. Different protein samples collected during the preparation of the soybean feedstock were loaded on a Coomassie-stained polyacrylamide gel (2 μg each lane): 1 homogenate before centrifugation, 2 oil body after the first centrifugation step, 3 oil body after the last washing step with sodium carbonate, 4 sodium carbonate supernatant, 5 dialysed protein mixture before chromatographic separation.
