蛋白组研究的三个主要步骤:
Separation of individual proteins by 2-D polyacrylamide gel electrophoresis (2-D PAGE)
Identification by mass spectrometry or Nterminal sequencing of individual proteins recovered from the gel
Storage, manipulation, and comparison of the data using bioinformatics

The study of proteins expressed by genomes Completion of the sequencing of the 1st draft of human genome
indicates there are approximately 250,000 proteins in the human genome Only 2-5% of proteins in human genome have been identified
