Difference in size between smooth and rough LPS molecules. Briefly, 0.8 μg of smooth and rough LPS were submitted to electrophoresis on a 10–20% polyacrylamide gradient gel in the presence of SDS and detected by silver staining. Apparent molecular weights of major bands, determined by comparison with molecular weight standards that were submitted to electrophoresis together with the samples, were 10.2 kDa for smooth LPS and 3.5 kDa for rough LPS.
