2D DIGE Data Analysis: In-Gel

The 2D DIGE In-Gel Data Analysis is ideal for comparing up to 3 samples, which can fit into one 2D DIGE gel. If your project involves comparing 4 or more samples2D DIGE Cross-Gel Analysis will be used. A typical 2D DIGE data analysis generates two main reports:

A. 2D DIGE Image Data Report by ImageQuant:

Gel images of individual samples and overlay of two sample images will be generated. In the overlay image, spots with green, red and yellow color indicate decreased, increased and similar expression, respectively.

B. 2D DIGE Quantitation Data Report by DeCyder: 

Quantitative analysis and comparison of all spots between different samples. The differential protein expression is assessed by Differential In-gel Analysis (DIA), giving the high accuracy and reproducibility. Here is a screenshot of DeCyder window, which contains:

  1. General statistic data (2 S.D. value, total spot number detected, number of decreased and increased spots etc.)
  2. Protein expression ratio (fold of change)
  3. 3D image view of the corresponding spot
