Abstract:
Technological advances in the field of genomics have given rise to the development of a new area called proteomics. Proteomics involves the analysis of all proteins expressed in a genome and uses a combination of sophisticated technologies such as two-dimensional electrophoresis, mass spectrometry and bioinformatics to identify and characterize proteins. This new area offers the potential to discover new biomarkers, improve diagnosis, and improve the prognosis of disease processes. This article presents an overview of proteomics importance and related technologies.
