Proteomics is the large-scale study of proteins. It is an emerging scientific research which can be applied for example to food (to find allergen for example) and plants research (for example to study plant pathogen response), as well as to biomedical research (clinical proteomics).
In particular, clinical proteomics is the science that aims to develop technologies for the treatment of patients through the analysis of proteomes of healthy and sick cells. This research area aimed to identify proteins that can be used as early markers in blood, urine, or tissues of cancer patients, or that may predict response to therapy or the relapse after treatment.
