The electrophoresis techniques are used in medicine, biochemistry, analytical chemistry, and biology to separate soluble and insoluble proteins, nucleic acids, chromosomes, viruses, as well as lysosomes, mitochondria, ribosomes and other cell organelles, red cells, tissue cells, and parasites. This book provides a view over the old electrophoresis techniques, as well as the recent developments in electrophoresis. Electrophoresis Fundamentals is based on the recent book Electrophoresis: Theory and Practice published in 2020 by De Gruyter. The previous book combines theory and technical applications with troubleshooting and problem solving. While Electrophoresis is intended for specialists, Electrophoresis Fundamentals is a book for laboratory technicians, students, biochemists, general practitioners, and more.
