Figure 3. Sequential protein extraction improved the SDS-PAGE profiles of P. ternata tuber proteins.

Figure 3

A, equal amounts of proteins (25 μg) from each extract were separated by SDS-PAGE. B, depletion effect of different concentrations of acetic acid. C, detection of glycoproteins in P. ternata tubers. Total tuber proteins were resolved by SDS-PAGE and visualized by CBB (protein load 25 μg) and Alcian stain (protein load 10 μg), respectively. Only the 11 kDa band was stained by Alcian staining, indicating a glycoprotein.
