Figure 1From: Secretion of polyhydroxybutyrate in Escherichia coli using a synthetic biological engineering approachSDS polyacrylamide gel and corresponding immunoblot of subcellular fractions for PhaP1:HlyA. C – cytoplasmic fraction, P – periplasmic fraction, M – membrane fraction, S – concentrated supernatant (media) fraction. The position of phasin bands varies from roughly 22–26 kDa.Back to article page
