Proteomics
Pronunciation
Definition 1
The study of the structure and function of proteins, including the way they work and interact with each other inside cells. (NCI Dictionary)
Definition 2
The global analysis of cellular proteins. Proteomics uses a combination of sophisticated techniques including two-dimensional (2D) gel electrophoresis, image analysis, mass spectrometry, amino acid sequencing, and bio-informatics to resolve comprehensively, to quantify, and to characterize proteins. The application of proteomics provides major opportunities to elucidate disease mechanisms and to identify new diagnostic markers and therapeutic targets. (NCI Thesaurus)
