A Closer Look at the Cell Lyser: Streamlining Cell Preparation Processes

Have you ever wondered what scientists look for inside a cell to study for tests like DNA, RNA  and proteins? The process can be complex but as science has advanced over the years the process of cell lysis has made it simpler. Before I get more complex let’s break down the term.


What is Cell Lyse?

A cell lyse is a device which helps you break open the cells which are the building blocks of other living organisms. The process is called Cell Lysis allowing scientists to perform tests like DNA, RNA and proteins. The components and analysis are important for scientists for conducting drug testing, specialised research and disease diagnosis. 

Application of Cell Lyse

Cell lysis is a critical unit for understanding cells in medical and biological processes. Some applications of cell lyse are:

  • Molecular diagnosis used for DNA pathogens identification
  • Immunoassays are used for a point-of-care diagnosis of different diseases
  • Protein purification is used for studying the function and structure of proteins
  • Cancer diagnostics helps in identifying cancer cells
  • Durg testing for testing new formulas and their reactions on cells
  • mRNA Transcriptome Analysis studies the expression of genes.

Microfluidic Devices in Cell Lyse

Different techniques have been used over the past few years to efficiently lyse cells. The method chosen depends on the ease of purification steps, target molecules and the quality of final products.

For the cell lysis process, microfluidic technology was involved which managed the tiny volumes of fluids (nanoliter or micrometre). The global market for the technology cell lysis reached 3.84 billion dollars in 2021.

The advantages of the microfluidic devices are:

  • Low reagent volume- using less material within a limited cost
  • High surface-to-volume ratio- enhancing reactions and efficiency of use
  • Low cost- minimizing expenses
  • Easy handling of small batches- used for several reasons

Microfluidic devices and perfect for cell lysis because of their small operating scale which fits the cell size. Researchers have developed methods through technology where they can analyse single cells using cell lysis methods. There are high opportunities in the medical and biological fields.

Understanding Cell structures

To better understand the method of cell lysing it is best to look into the cell structures. Cells are surrounded by cell membranes which protect anything from entering or exiting. Basically, it acts like a protective boundary.

There are two main types of cells:

Eukaryotic (Like human and animal cells)- these cells have a cytoplasmic membrane that encloses all cell contents.

Prokaryotic (Like bacteria)- these cells have additional layers along with a cell wall and sometimes a strong membrane which makes it difficult to lyse.

How does Cell Lysis Work?

Cell lysis helps to break down the cell membrane to get access to the internal area of the cell. It can be done through detergents that react with the cell membrane to create pores. If the detergents do not work, the process of sonetization (sound waves) or homogenization (mechanical disruptions) is used.

It is very important to assess the component and the way it responds to certain chemicals. The human or animal cell membranes do break down easily but the prokaryotic doesn’t. there are certain chemicals like SDS, Triton X-100, CTAB and other chemical mixtures to lyse them.

Future of Cell Lysis

Innovations like automation and throughput systems are successful in making the process fast and efficient. The advancement in the field is important for medical reasons. As technology is changing researchers making further advancements through large-scale studies and industrial applications. Real-time analysis and bioinformatics are the two new areas of development that can transform the cell lysing process. 


Cell lysis is a technique in modern biology and medicine which helps scientists understand and study the inner components of the cells. Tools like cell lyse with microfluidic technology have made it easier to perform the method. The development is important for diagnosis, drug testing and further development.
