Two-dimensional difference gel electrophoresis of protein extracts from SHMEC, THMEC 40 d, THMEC 80 d. (A) Schematic of images per time point. Green and red gels correspond to Cy3 and Cy5 labeled samples, respectively. Blue arrow indicates the location of maspin (Master Spot #919) on a 2D-Gel image from each time point. (B) A representative image of a 2D gel. This image is of Gel 10 Internal Standard labeled with Cy2. Circled spots are those identified as being significantly (FDR corrected p < 0.05) differentially expressed between HMEC-SV40-hTERT/THMEC 40 d or HMEC-SV40-hTERT/THMEC 80 d, or ANOVA. Spot numbers for unique IDs correspond to the Master Spot numbers assigned by DeCyder. For each numbered spot, a topographic map of signal intensity is displayed with the area used to calculate intensity shown in yellow.
