A lysis buffer is a solution which is used to breakdown or separate the components of cells. Like all buffers, it is supposed to maintain the pH within a narrow range.
Lysis buffers are used when analysis of separate components of the cell as desired - such as DNA isolation.
MgCl2 in the lysis buffer helps to stabilize enzymes that are involved in the lysis process, such as nucleases and proteases. It also helps in maintaining the integrity of nucleic acids by minimizing degradation during the lysis step. MgCl2 is essential for the efficient extraction of DNA or RNA from cells by promoting the disruption of cell membranes.
The function of lysis buffer in DNA extraction is to break down the cell membrane and nuclear envelope, releasing the DNA from the cell. This allows the DNA to be isolated and purified for further analysis.
A commonly used lysis buffer recipe for protein extraction includes components such as Tris-HCl, sodium chloride, NP-40, and protease inhibitors. This buffer helps break down cell membranes and release proteins for further analysis.
The lysis buffer helps break down the cell membrane and nuclear envelope, releasing DNA from the cell. This allows the DNA to be isolated and extracted for further analysis in the laboratory process.
To make lysis buffer, mix a detergent like SDS or Triton X-100 with a buffer solution like Tris-HCl. Adjust the pH to around 7.4 and add protease inhibitors if needed. This solution helps break open cells and release their contents for further analysis.

EDTA in lysis buffer helps to chelate divalent cations (such as Mg2+ and Ca2+) which are cofactors for nucleases, preventing degradation of nucleic acids. This helps to preserve the integrity of RNA and DNA during the lysis process.
To protect protein during thawing and freezing

Bromophenol blue is added to lysis buffer as a tracking dye to monitor the progress of protein electrophoresis. It helps visualize the sample migration through the gel during SDS-PAGE by imparting a blue color to the proteins.
The lysis buffer is used in DNA extraction to break down the cell membrane and release the DNA from the cell. It contains chemicals that disrupt the cell structure, allowing the DNA to be isolated and purified for further analysis.
Urea disrupts hydrogen bonding and denatures proteins, helping to break down cell membranes and release cellular contents during lysis. It also helps to solubilize proteins by disrupting non-covalent interactions, aiding in protein extraction and purification.
Triton X-100 is used as a lysis buffer for DNA separation.
Glucose is added to increase the osmotic pressure outside the cells. Tris is a buffering agent used to maintain a constant pH ( = 8.0). EDTA protects the DNA from degradative enzymes (called DNAses); EDTA binds divalent cations that are necessary for DNAse activity.
