TritonX-100 was used for Remove the SDS-From the crude protein, during homogenization the cell lysis buffer as contain SDS otherwise no need.
it solubilize the lipids and protein and remove them.
beta- merceptoethanol denatures the protein by breaking the sulphur bridges in it.
it is non-ionic detergent.so it act as non-denaturing agent and membrane protein are not denature.
phenol is used in order to remove protein impurities from the DNA to yield pure dna while chloroform prevents shearing of DNA during isolation.
sodiom acetat reaction with membrane protein and cause that persipitate and help to dna isolation
The role of NaCl or sodium chloride in RNA isolation is part of the denaturing process. It is often called the wash step.
Triton X-100 is used as a lysis buffer for DNA separation.
The isolation (or extraction) of proteins requires a different method that those for organic molecules. Proteins are extremely sensitive to temperature and ionic conditions. Therefore, the protocol for the isolation of a protein should take into consideration the preparation of the correct buffers and experimental methods to keep the protein intact so it does not degrade during the extraction process. Protein are typically extracted from live cells so the isolation protocol should include disrupting the cell and removing the protein undamaged. With organic molecules however, liquid-liquid extraction or 2-phase extraction may be carried out (depending on the properties of the organic substance)
It sequester carbohydrates in the solution
Sodium acetate buffer helps by reacting with the membrane protein and precipitating them, thus facilitating the dna isolation.
Sucrose performs the function of osmoregulation in the protocol of DNA isolation from blood
it act as as a cationic detergent for the isolation dna from the given sample
