Proteomics Study of Rice Embryogenesis: Discovery of the Embryogenesis-Dependent Globulins. Electrophoresis 2012, 33, 1129–1138.
In general, the complex process of embryogenesis results from the action of a coordinated network of genes. Here we carefully analyzed the rice embryos using two-dimensional gel electrophoresis (2DE) and matrix-assisted laser desorption-ionization time of flight/time of flight mass spectrometry (MALDI TOF/TOF MS) to identify the stage-dependent proteins. 53 spots were identified from the total of 66 spots which were discovered to be regulated during embryogenesis, and the further examination result showed that the multiple forms of globulins were produced as a result of enhanced proteolysis during embryogenesis, indicating that these globulin forms may serve as chaperone proteins participating in the formation of multiple protein complexes during embryogenesis.
Figure 1. Workflow of Protein Identification
Standard bioinformatics analysis
- Statistical analysis and quality control
- Protein identification
- Protein GO category analysis (only for LC-MS/MS)
- Protein COG category analysis (only for LC-MS/MS)
- Protein pathway analysis (only for LC-MS/MS)
- SDS-PAGE slices or 2D-PAGE gel particles with a volume ≥ 1.5mm3. Coomassie stain is preferred over silver, but both staining spots should be visible. If using silver, do not fix the gel with glutaraldehyde. Ensure that samples are sent within one week after gel electrophoresis, otherwise, the gel should be kept at 4°C.
- Single protein identification:
Solution or powder samples which are soluble in water: protein ≥ 10µg.
Powder samples that are sparingly soluble in water: protein ≥ 50µg.
