1. Quantitative comparison of a human cancer cell surface proteome between interphase and mitosis
Immunostaining of HeLa cells probed for FITC‐labeled streptavidin and DNA and the merge streptavidin (red) and DNA (blue). Cell surface was labeled using amine biotinylation. Scale bar, 10 μm. Western blot analysis of cell surface preparation. The surface‐biotinylated cells were lysed using a detergent containing lysis buffer, incubated with and then eluted from streptavidin beads (i.e., cell sur. fraction). Cell surface fraction and the whole‐cell lysate were blotted against a cell surface protein, EGFR, and a cytoplasmic protein, actin. Workflow of the cell surface proteome. Cell surface labeling and isolation of cell surface proteins in SILAC‐labeled interphase versus mitotic HeLa cells are shown. Schematic of all identified proteins (blue circle) and cell surface proteins (pink circle). Cell surface/plasma membrane proteins were identified based their GO annotations; their distribution is shown in a pie chart (top). Source data are available online for this figure.
