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.
MgCl2 is used to preserve the integrity of membrane system by counteracting the fixed negative charges of membrane phospholipid. Depending on what you want to extract, it tries to protect the component you are interested in (DNA/RNA/red blood cells, etc) from being lyzed by broken-open lysosome for instance.
MgCl2=95grams per mole so 105g/95g is 1.10 mols of MgCl2
MgCl2 Molarity = moles of solute/Liters of solution ( 250 ml = 0.250 L ) Get moles MgCl2 80 grams MgCl2 (1 mole MgCl2/95.21 grams) = 0.8402 moles MgCl2 Molarity = 0.8402 moles MgCl2/0.250 Liters = 3.4 M MgCl2 ----------------
The synthesis equation for MgCl2 is Mg + Cl2 -> MgCl2. The decomposition reaction is MgCl2 - heat-> Mg + Cl2.
No, MgCl2 is not a base. It is a type of salt that is known for its high solubility in water.

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.

MgCl2
yes mgcl2 is aqous solution
No, MgCl2 is not a base. It is a type of salt that is known for its high solubility in water.
Need moles MgCl2 75.0 grams MgCl2 (1 mole MgCl2/95.21 grams) = 0.7877 mole MgCl2 ================now, Molarity = moles of solute/Liters of solution ( 500.0 milliliters = 0.5 Liters ) Molarity = 0.7877 moles MgCl2/0.5 Liters = 1.58 M MgCl2 solution --------------------------------
MgCl2 will dissolve in water to form?
