A two-dimensional gel electrophoresis(2-DE) system for the separation of myofibrillar proteins from silver carp was established and optimized in this study. The key factors of isoelectric focusing(IEF) and the p H gradient of immobilized p H gradient(IPG) strip were selected as the main factors affecting 2-DE in this paper. We loaded 120 μg of protein onto the 17 cm p H 4-7 IPG strip, and the IEF program III was as follows: 50 V for 15 h, three-stage desalting involving 250 V for 2 h, 1 000 V for 2.5 h and ...
