Figure 1From: Comparative proteomic analysis of spermatozoa isolated by swim-up or density gradient centrifugation2-dimensional separation of sperm cell proteins. Representative protein maps of Sypro Ruby-stained gels corresponding to one subject. Sperm cells were obtained by DC or SU. Isoelectric focusing covered the range pI 3- pI 11. Molecular masses (Mr) are indicated on the left axis.Back to article page
