Understanding the functional, behavioral, and biochemical characteristics of a specific cell line requires the use of relatively pure cell cultures, as cells obtained from tissues, blood, or other body fluids are typically mixtures of various cell types. Each type of cell may exhibit distinct metabolic processes, biological properties, and physical or chemical parameters, which can complicate analysis when working with mixed populations.
There are two main categories of methods used to isolate different cell lines. The first involves physical properties such as size, density, and charge. Techniques include low-speed, high-capacity centrifugation, physical adsorption, gel chromatography, and cell electrophoresis. The second category relies on biological differences, such as cell surface markers or adhesion properties, and includes methods like the plaque formation technique and monolayer immunoabsorption.
Among these techniques, low-speed, high-capacity centrifugation is widely used due to its simplicity and effectiveness. It separates cells based on their size and density, and it allows for the use of various separation media with minimal damage to the cells. This method is versatile and suitable for a wide range of research applications, making it one of the most commonly used tools in biological laboratories.
When studying cellular components—such as the nucleus, mitochondria, lysosomes, Golgi apparatus, and microsomes—it's essential to separate and purify these subcellular structures from whole cells. Researchers have long been interested in understanding the unique chemical compositions, metabolic activities, and functions of these components. Although early attempts at organelle isolation date back over a century, it wasn't until the 1940s that advances in ultracentrifuge technology and cell homogenization enabled more precise and reliable methods. These techniques allow scientists to obtain relatively pure organelles and even large molecular complexes, making them crucial for modern cell biology research.
The key to this process is the use of ultracentrifuges, which apply extremely high speeds to separate cellular components based on their density and size. This method, known as differential centrifugation, remains a fundamental tool in cellular and molecular biology, enabling detailed investigations into the structure and function of subcellular compartments.
