An Australian scientist, Marc Wilkins, coined the term in 1994, to refer to the large-scale study of an organism's proteins. Proteins, not genes, do the work of biology. Proteins are to genes as buildings are to blueprints. The goal of proteomics is to make sense of the genetic code through an understanding of proteins. Biologists have always looked at proteins, but until recently they have studied them individually.
Proteomics proposes to examine thousands of proteins at once.
The separation of ions in an electric field. For macromolecules, this is usually done in a water-swellable matrix like polyacrylamide or agarose which perform sieving functions and reduce convection. The study of the functions of genes and their interrelationships. Genome sequence is structure only. While bioinformatics allows us to infer function, in some cases, it is necessary.
