Proteomics: Principles, Techniques and Applications by Dr. Natasha Beeton-Kempen - University of Zambia - Biomedical Sciences-unza

Description

This article provides a comprehensive overview of proteomics, the large-scale study of proteins, their structures, functions, and interactions. It defines the proteome as the complete set of proteins an organism can express, which is dynamic and varies by cell type, time, and condition. The material details key proteomic questions regarding protein identification, quantification, localization, post-translational modifications, and interactions. It outlines both low-throughput techniques like antibody-based assays, gel electrophoresis, and chromatography, and high-throughput methods such as protein microarrays and mass spectrometry, explaining workflows including ionization, mass analysis, and tandem MS. The article compares top-down and bottom-up proteomic approaches, discusses the challenges of data analysis, and highlights diverse applications in personalized medicine, biomarker discovery, drug development, agriculture, and astrobiology. Authored by Dr. Natasha Beeton-Kempen, this resource is tailored for tertiary students in biomedical sciences, biochemistry, and biotechnology programs at the University of Zambia, offering essential revision material on modern analytical techniques for exam preparation and research insight. The notes serve as valuable university reference material, integrating core principles with practical methodologies to understand how proteomics deciphers biological complexity at the protein level. Review this guide to grasp the technological foundations and expansive utility of proteomics in advancing scientific and medical knowledge.
