Fig. 4From: iTRAQ-based analysis of sperm proteome from normozoospermic men achieving the rescue-ICSI pregnancy after the IVF failureRepresentative spectrum of sperm protein sequenced by 5800 MALDI TOF/TOF mass spectrometry. The MS/MS map is identified as respectively for zona pellucida-binding protein 1 (ZPBP1). The sequence of precursor at m/z 1618.7771 is assigned to the peptide of EPHYYYTFQAR. The enlarged map represents the ions labelled by iTRAQ reagentBack to article page
