The primary purpose of a buffer is to control the pH of the solution. Buffers can also play secondary roles in a system, such as controlling ionic strength or solvating species, perhaps even affecting protein or nucleic acid structure or activity. Buffers are used to stabilize nucleic acids, ...
Uses of Tris-HCL buffer solution Although it has been used in nucleic acid and protein solvents, this is not the only use. It can also be used in the following ways: 1, Protein growth in different PH conditions, because of its low ionic strength can be used ...
