    2000-8-15 · Proteome analysis is most commonly accomplished by a combination of two-dimensional gel electrophoresis (2DE) to separate and visualize proteins and mass spectrometry (MS) for protein identification. Although this technique is powerful, mature, and sensitive, questions remain concerning its ability to characterize all of the elements of a proteome. In the current study, more than 1,500 ...

  • Evaluation of two-dimensional gel electrophoresis

    2017-1-23 · Saturation of pigments extracted from mature cells in nonionic surfactant aqueous solution. By putting a low density of mature cells (2 g/L) in a TX aqueous solution, the intracellular pigments were extracted and gradually decreased as the TX concentration increased (Fig. 2, a2).Nearly 90% of the intracellular pigments could be extracted to the extracellular space when the TX concentration ...
