The basic concepts and principles of gel electrophoresis are illustrated in this all-inclusive book. Gel electrophoresis covers numerous gel-based division methods that rely mostly on fractionating biomolecules on the basis of molecular weight using electrophoretic current. A majority of people should be in agreement to the fact that it is one of the essential supports of molecular biology. In this book, the writers have attempted to provide an account of basic principles of gel-based division together with exceptional applications of this flexible method. We have tried to keep the data of the book simple and all-inclusive, and we intend to help students and experts in gaining more knowledge regarding the topic.
