Figure 3From: Size and Shape of Protein Molecules at the Nanometer Level Determined by Sedimentation, Gel Filtration, and Electron Microscopy Determination of R s of BsSMC by gel filtration. The column was calibrated by running standard proteins BSA, catalase, and thyroglobulin over the column, then BsSMC. BsSMC eluted in fraction 14.2, which corresponds to an R s of 10 nm on the extrapolated curve. In repeated experiments, the average R s was 10.3 nm [19].Back to article page
