Purpose of the Study:

  • To define the era of proteomics, focusing on elucidating the expression, structure, and function of all proteins.
  • To highlight the critical role of proteins in driving life's activities.

Main Methods:

  • Two-dimensional gel electrophoresis
  • Two-dimensional High-Performance Liquid Chromatography (HPLC)
  • Mass spectrometry
  • Bioinformatics

Main Results:
