PMSF is a protease inhibitor. During the protein extraction, the proteases present in the cell lysate may digest the disered proteins, to prevent this PMSF is added!
Acetone is used in protein extraction to precipitate proteins from solution. When added to a protein sample, acetone causes the proteins to denature and aggregate, leading to their precipitation. This allows for the separation of proteins from other components in the sample.
Function of MgCl2 in Protein Extraction Our work shows that MgCl2 in osmotic shock buffer at a concentration of 2 mM improves protein extraction and reduces contamination with other proteins. To achieve a simplified purification procedure for rhGM-CSF, work focused on adjusting the pH of the buffer and applying the correct salt concentration.
2-mercaptoethanol is a reducing agent that helps break disulfide bonds in proteins, allowing for better extraction of plant proteins. By disrupting these bonds, 2-mercaptoethanol helps to solubilize proteins and prevent their aggregation during the extraction process.
Detergent is added to the extraction buffer to help solubilize and denature proteins by disrupting protein-protein and protein-lipid interactions. This aids in releasing proteins from cellular structures and membranes, thereby improving the efficiency of protein extraction. Additionally, detergent helps to prevent protein aggregation during the extraction process.
glycerol increases the stabilization of the protein by decreasing the surface tension of water

Salt helps to increase the solubility of certain biomolecules, such as proteins or DNA, in the extraction solution. This can help to maximize the yield of the target biomolecule during the extraction process. Additionally, salt can help to disrupt protein-protein or protein-nucleic acid interactions, aiding in the separation of the biomolecule of interest from other cellular components.
Protein precipitation using ethanol can help to concentrate proteins in biological samples by causing them to clump together and separate from the solution. This can increase the efficiency of protein extraction by making it easier to isolate and purify the proteins of interest.
Salt is added to the extraction solution to increase the ionic strength, which helps in disrupting protein-protein and protein-DNA interactions, thereby aiding in the extraction of the target biomolecules. It also helps to stabilize the structure of proteins and nucleic acids during extraction and prevents their degradation.
Chloroform is commonly used in RNA extraction to separate RNA from other cellular components. It helps in the denaturation of proteins and the dissolution of lipids during the extraction process. Chloroform aids in the formation of a distinct organic phase where RNA can be collected.

Phenol chloroform isoamyl alcohol is used in plasmid DNA extraction to separate DNA from proteins and other contaminants. Phenol denatures protein structures, allowing them to be separated from the DNA. Chloroform and isoamyl alcohol are used to further purify the DNA by removing residual phenol and debris.
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.
