Overview of Proteomics

The era of genomics has brought tremendous advancement especially in the fields of medicine and life sciences. Despite the overwhelming growth of information generated from genomics research, a huge gap specifically in relation to genome expression persists, and became increasingly noticeable. This has sparked interest in studies of proteins expression and eventually added limelight to the field of proteomics. Aside from the need to fill the gap, the emergence of proteomics is also deemed to have occurred due to the advancement in capabilities of research techniques, particularly in the separation and identification of proteins. Proteomics has since progressed and is slowly extending into other research as well as applied subspecialties. This brief overview was written to provide a basic and simplified understanding of proteomics in view of its growing interest from newcomers to the area.
