Cell lysates are an important tool used by many researchers in the biotech industry. Cell lysates are produced by disrupting cells to release intracellular contents release and isolate the contents, such as proteins, nucleic acids, and other biomolecules. The resulting solution can be used in a wide range of research applications (Understanding the Uses of Mammalian Cell Lysates in Research, 2024). In this blog we will take a closer look at what lysates are and their applications in research.
A Closer Look at Lysates
Cell lysates are solutions used by researchers that are derived from the contents of a cell that has been broken open. To break open the cell, researchers will typically use methods such as sonication or chemical lysis to disrupt the cell membrane, allowing for the cell contents to be released for analysis. The resulting solution is comprised of a complex mixture of proteins, lipids, and other molecules that are useful in a wide variety of applications (Understanding the Uses of Mammalian Cell Lysates in Research, 2024).
There are two main types of cell lysates that researchers can generate for use in their research. First are Whole Cell Lysates. Whole cell lysates contain a broad mixture of cellular components, including cytoplasmic, membrane-associated, and nuclear proteins. The other type of available lysate is a Nuclear Extract, which contain mostly nuclear proteins from inside the cell. The preparation of cell lysates is a routine workflow in many molecular biology labs around the world, and lysates provide valuable insights to researchers on cellular reactions, components, and functioning inside the cells (Cell Lysate: Definition, Applications, & Industry Uses, 2022).
Applications of Cell Lysates
Cell lysates are useful in a wide range of research applications, including life science research, molecular biology, biochemistry, and are used commonly in assay workflows in cell biology labs. Some specific applications for prepared lysates include being used in immunoassays, studying cellular heterogeneity in cell cultures, metabolic studies, genomics, molecular diagnostics of pathogens, and downstream processes including diagnostics, drug screening, protein purification, and more (Cell Lysate: Definition, Applications, & Industry Uses, 2022).
There are a few reasons why researchers might consider using cell lysates in their research, including flexibility of use, low cost, and valuable insights provided by the sample’s components. Cell lysates are relatively cheap to produce or procure compared to purified proteins. On top of that, because cell components are readily available for analysis, lysates can be used in a variety of ways to gather data on different cell processes. Cell lysates are especially flexible when it comes to using them in assay applications. Lysates can be used in a variety of assay applications, including immunoassays, enzymatic assays, SDS-PAGE, and Western blotting, making them a great option for a variety of researchers (Understanding the Uses of Mammalian Cell Lysates in Research, 2024).
