Methods Mol Biol. Plant Physiol. Zargar, S. Further the total number of protein spots detected on the gel were compared for seeds, leaves and flowers that were processed by Protocols 1, 2, and 3 Table 1. Here, we report tissue-specific protein extraction protocols representing vegetative young leavesand reproductive flowers and seeds organs and their subsequent analysis on 2-dimensional gel electrophoresis. Except for P, all other methods allowed the extraction of protein with comparable yields Table 1with the L and T methods resulting in the highest yields. Structural and metabolic transitions of C4 leaf development and differentiation defined by microscopy and quantitative proteomics in maize. Flow chart depicting the steps of protein extraction from seed, leaf and flower using three different protocols. View on PubMed. Electrophoresis ; 7: 52—4.

    Identification of phosphoproteins in Arabidopsis thaliana leaves using polyethylene glycol fractionation, immobilized metal-ion affinity chromatography, two-dimensional gel electrophoresis and mass spectrometry. This behavior probably results from the fact that third maize leaves are a non-recalcitrant tissue that contain small amounts of interfering substances.

    For optimal clarity, protein spots were detected by adjusting different parameters, i. Background Protein extracts obtained from cells or tissues often contain interfering substances, which must be removed for preparing high-quality protein samples [ 1 ].

    A number of protein extraction methods have been applied to various of total proteins, which was initially developed by Damerval et al.

    Total protein extraction with TCAacetone.

    We describe a procedure allowing extraction of total proteins that performs efficiently with a large We also describe protein solubilization prior to IEF, either in classical rod gels or in IPGs, C. Damerval, M. Zivy, F. Granier, D.

    Cleavage of structural proteins during the assembly of the head of the bacteriophage T4.

    These non-recalcitrant properties are a key feature to achieve high-quality 2DE maps when methods that do not rely on a protein purification step are used to extract protein, such as the method L described in this work.
