Acquiring Metastatic Competence by Oral Squamous Cell Carcinoma Cells Is Associated with Differential Expression of -Tubulin Isoforms
Figure 3
Scattergram depiction of DIGE data to generate protein expression profile of 686Tu and 686Ln cells. Each dot represents a protein detected in 686Tu and 686Ln cells. The dots are expressed as bigger pixel volume in either cell (right -axis), and plotted against log scale of pixel volume ratio between 686Tu and 686Ln ( axis), with 686Tu as standard. Two vertical lines indicate two-fold difference limits between the two cells. Left -axis is number of spots at certain pixel ranges. Related pink curve is actual distribution of spots versus their pixel volume ratio and green curve is normalized Gaussian distribution (). Arrows indicate two protein spots to be studied.
