An Improved System of Two-dimensional Electrophoresis for the Tung Tree Seed Protein Separation

  • Received Date: 2012-06-26
  • In order to construct a basis for the tung trees protein research, some key factors which could impact on the results of the protein separation were studied and an improved system of two-dimensional electrophoresis were built successfully including the suitable protein extraction method (TCA-acetone combined with phenol), the solution buffer (7 mol·L-1 urea, 2 mol·L-1 thiourea, 4% CHAPS, 65 mmol·L-1 DTT and 2% IPG buffer), the volumes of loading protein (700 μg) in IEF and the better conditions for the SDS-PAGE (15% separation gels and constant 5W for 8 h).

Abstract: In order to construct a basis for the tung trees protein research, some key factors which could impact on the results of the protein separation were studied and an improved system of two-dimensional electrophoresis were built successfully including the suitable protein extraction method (TCA-acetone combined with phenol), the solution buffer (7 mol·L-1 urea, 2 mol·L-1 thiourea, 4% CHAPS, 65 mmol·L-1 DTT and 2% IPG buffer), the volumes of loading protein (700 μg) in IEF and the better conditions for the SDS-PAGE (15% separation gels and constant 5W for 8 h).
