Fig. 4

A composite orthorectified image derived from #4 2D-DIGE images of phosphoproteins extracted from control and failing rat hearts. a Means The colors represent the average difference between the controls and failing images and range from light blue (turquois) (small average differences) through dark blue (significant large average differences) (see color scales). b Standard deviations of means: The colors represent the average difference between the controls and failing images and range from light purple (small average differences) through dark purple (123) (see color scale) (n = 4). Greatest difference in phosphoprotein density and variability is noticed in the upper right quadrant
