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.

What is the role of 2-mercaptoethanol in plant protein extraction?
To oxidise the cysteins
What is the role of acetone in protein extraction?
acetone degrades protien
What is the role of PMSF in protein extraction?
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!
Role of saline tris edta in DNA extraction?
Its purpose is to isolate DNA from a protein mixture.
What does NaCl do during protein extraction?
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.

What is the role of sodium acetate in DNA extraction?
sodiom acetat reaction with membrane protein and cause that persipitate and help to dna isolation
What is the role of beta mercaptoethanol in DNA extraction?
to remove tannins and polyphenols which are readily present in crude plant extracts
What is the Role of chloroform in RNA extraction?
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.

Role of mgcl2 in DNA isolation?
mgcl2 work as a cofactor and they enhance the enzymatic reaction..
Role of mgcl2 in DNA extraction by phenol chloroform method?
TRIS (tris(hydroxymethyl)aminomethane): Firstly it's used to get the right pH for DNA extraction, but Tris is preffered over other buffers because Tris interacts with the lipopolysaccharides present on the outer membrane which helps to permeabilize the membrane. This effect is enhanced with the addition of EDTA (ethylenediaminetetraacetic acid), which is a chelating agent that captures metal ions (like Ca2+). MgCl2: When membranes are busted by TRIS, there is no compartmentalization in the solution anymore. MgCl2 is then used because it binds to DNA and thus protects it against DNase proteins that are now (because of lack of membranes) in direct contact with your DNA. The binding of MgCl2 to DNA denies access of DNase to the DNA, and your DNA will not be broken down.
What role does a cheese cloth play in DNA extraction?
It plays a role.
What is the role of methanol in the extraction of chlorophyll?
serves as catalyst
