3 Figure 2 Difference gel electrophoresis (DIGE) images of CyDye-labelled human sperm proteomes of (A) type 1 diabetic, (B) non-diabetic obese, and (C) slim clinically healthy fertile individuals. (D) shows the image of the internal standard. The arrows in A and B indicate the position of sperm proteins exhibiting significantly increased (blue) or decreased (red) average abundance ratios (P⩽0.05). Corresponding gel discs were excised and subjected to tryptic proteolysis and mass spectrometric peptide identification. The positions of the identified differentially expressed proteins are also indicated in (C). For overview reasons, the positions of a limited number of additional sperm proteins are indicated (D). The identified proteins are annotated by their gene names according to the NCBInr protein database (for full protein names, see Tables 2–4).
