Zebrafish is a powerful model to analyze vertebrate embryogenesis and organ development. Although a number of genes have been identified to specify embryonic development processes, only a few large-scale proteomic analyses have been reported in regard to these events to date. Here the total proteins of a single embryo were analyzed by urea-, sodium deoxycholate (SDC)-, and performic acid (PA)-assisted trypsin digestion strategies coupled to capillary liquid chromatography-tandem mass spectrometry (CapLC-MS/MS) identification. In total, 509 and 210 proteins were detected from the embryos at 72 and 120 hours postfertilization (hpf), respectively, with a false identification rate of less than 1%. Approximately 95% of those proteins could be observed by combining the urea- and SDC-assisted digestion strategies, suggesting that these two methods are more effective than the PA-assisted method. Compared with 0.5% SDC, 1% SDC was more effective to identify proteins in zebrafish embryos. In addition, removal of the predominant yolk proteins could significantly improve protein identification efficiency. Our study represents the first overview of the protein expression profile of a single zebrafish embryo at 72 or 120 hpf. More important, this single individual proteome methodology could be applied to multiple development stages of wide-type or mutant embryos, providing a simple and powerful way to further our understanding of embryonic development.
