Biochemical Techniques and Instrumentation

4.1.1. Introduction

Centrifugation is one of the most important and widely applied research techniques in biochemistry, medicine, cellular and molecular biology for the isolation of cells and viruses, separation of subcellular organelles and isolation of macromolecules such as DNA, RNA, proteins or lipids. Centrifugation is carried out by a centrifuge that uses centrifugal force or g-force to isolate suspended particles from their surrounding medium.
