Proteomics Protein +Genome Proteome Proteome Proteomics
50
How Proteomics Can Help Drug Development
51
Definitions of Proteomics First coined in 1995 Be defined as the large-scale characterization of the entire protein complement of a cell line, tissue, or organism. Goal: -To obtain a more global and integrated view of biology by studying all the proteins of a cell rather than each one individually.
52
Proteomics Origins In 1975, the introduction of the 2D gel by O’Farrell who began mapping proteins from E. coli. The first major technology to emerge for the identification of proteins was the sequencing of proteins by Edman degradation picomole MS technology has replaced Edman degradation to identify proteins femtomole
