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 degrades protien
To oxidise the cysteins
Its purpose is to isolate DNA from a protein mixture.
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.
In solution, NaCl can split into Na+ and Cl- ions. These ions are indeed needed to stabilise the hydrophilic residues of the protein molecule that are exposed on the surface. So NaCl is a stabilising agent in various protocols even in the extraction, but it does not has any role in lysing the cells or neutralising other biomolecules.

sodiom acetat reaction with membrane protein and cause that persipitate and help to dna isolation
chloroform is used to denature protein and settle it in the bottom during rna extraction ,also it helps to form organic and inorganic layers in which rna is dissolved in inorganic layer.

It plays a role.
to precipitate protein.
glycerol increases the stabilization of the protein by decreasing the surface tension of water
serves as catalyst
lyses cells
