Proteomics is something new in the field of biotechnology. It is basically the study of the proteome, the collective body of proteins made y a person’s cells and tissues. Proteome research permits the discovery of new protein markers for diagnostic purposes and of novel molecular targets for drug discovery. It is obvious that without the help of instruments like mass spectrometers, electrophoresis equipments and x-ray crystallographs, proteomics would be impractical.The abundance of information provided by proteome research is entirely complementary with the genetic information being generated by genomic research. Proteomics will make a key contribution to the development of functional genomics. The combination of proteomics and genomics will play a major role in biomedical research and will have a significant impact on the development of diagnostic and therapeutic products of the future.
