(a) Standard calibration curve based on the log(molecular weight) of four different standard proteins plotted against Kav. The circle and triangle on the standard curve indicate the positions of SghR and SghA, respectively (depicted based on the Kav value). (b) Gel-filtration chromatography elution profile of SghA (solid line) and SghR (dashed line) used for molecular-weight calibration. |
